You have an expectation of privacy in location data that reveals your movements in the physical world, and even short-term surveillance of these movements is a search subject to the Fourth Amendment, the U.S. Supreme Court ruled today in Chatrie v. United States.  

The case involved geofence warrants, a form of dragnet surveillance police have used to vacuum up location data from electronic devices of people who happen to be in the vicinity of a crime. EFF had joined the American Civil Liberties Union, the ACLU of Virginia, and the Center on Privacy & Technology at Georgetown Law in filing an amicus brief in the case.

The decision in Chatrie is important: It is the first digital surveillance decision by the Court since its landmark 2018 ruling Carpenter v. United States, which involved prolonged tracking of people’s movements using cell phone location data. The new case expands that ruling by confirming that even shorter-term surveillance of location data can constitute a search because it can still reveal “private matters,” including “a wealth of detail about a person’s familial, political, professional, religious, and sexual associations.”  

The case is also important because the Court also recognized the records generated by the apps on a user’s phone—records we necessarily share with third-party tech company—are a user’s “own” and require Fourth Amendment protection. This is true, regardless of whether those records are “emails, documents, photographs, [ ] calendars” or location data. This will likely have broad implications for data generated by other apps on our phones, even if we click “agree” to sharing that data with third-party tech companies.  

Geofence warrants don’t name a suspect or a specific individual or device the way typical warrants do. Instead, they compel companies—almost always Google—to provide information on every electronic device in a given area during a given time period. This creates a high risk of suspicion falling on innocent people and can reveal sensitive and private information about where individuals have traveled in the past. 

Geofence warrants are the digital equivalent of police going person to person, home to home, without suspicion that any device holder has a connection to a crime. This turns innocent bystanders into suspects, just for being in the wrong place at the wrong time.  

In Chatrie, a 2019 geofence warrant compelled Google to search the accounts of all its hundreds of millions of users to see if any one of them was within a radius police drew around a Northern Virginia crime scene. This area amounted to several football fields in size and encompassed numerous homes, businesses, and a church. 

A federal district court in Virginia in 2022 held that the geofence warrant plainly violated  the Fourth Amendment. If the police want to get information on every device in the area, they must also establish probable cause to search every person in the area, the court said. The judge noted the government lacked particularized probable cause as to every individual within the geofence, which swept up innocent people and covered over 70,000 square meters in a busy area. 

The decision set an important precedent in finding the warrant overbroad and unconstitutional and was later followed by a 2024 federal Fifth Circuit Court of Appeals ruling holding that geofence warrants are “categorically prohibited by the Fourth Amendment.” However, the Chatrie lower court allowed the government to use the evidence it obtained because it relied on the warrant in “good faith.” A much divided en banc panel of the U.S. Court of Appeals for the Fourth Circuit in 2025 affirmed this “good faith” finding in the lower court’s opinion. 

Google in 2023 announced changes to how it stores location data, with the effect of eventually making it impossible for the company to respond to geofence warrants. Since July 2025, mass geofence searches of Google users’ location data have not been possible.  

However, Google is not the only company collecting location data, nor the only way for police to access mass amounts of data on people with no connection to a crime. As we’ve written about extensively, data brokers collect and aggregate location data from many different apps on our phones and provide that data to police. And police can use “cell tower dump” warrants to get access to data on everyone within range of specific cell towers. Suspicionless searches like these drag a net through vast swaths of information in hopes of identifying previously unknown suspects—ensnaring innocent bystanders along the way. 

Chatrie could have wide-ranging implications beyond location data as well. The Supreme Court affirmed that app data is subject to the Fourth Amendment, because users “reasonably view” it as their own and reasonably expect it “to be shielded from the ‘inquisitive eyes’ of the government.” Justice Gorsuch, in an opinion concurring in the judgment, called location data a user’s “personal property,” no different from myriad other “effects” explicitly protected by the text of the Fourth Amendment.  As the Court concluded, “the point of carrying smartphones is to use is to use what is on them,” so the Fourth Amendment has to protect more than just location data generated by the act of carrying the phone itself. 

The Court ultimately did not decide whether the particular warrant at issue in Chatrie was “reasonable” or whether the “good faith” doctrine applied. The case now heads back to the Fourth Circuit Court of Appeals to address these questions.  

But regardless of how the Fourth Circuit rules on remand, this Chatrie opinion will shape how lower courts address police access to location and other data going forward. We look forward to citing Chatrie to press future courts to recognize broad Fourth Amendment protections for user data.

Interesting research on a new class of weak RSA keys: keys with lots of zeros. It turns out that these keys are out in the wild.

The badkeys project is an open-source service that checks public keys for known vulnerabilities. While developing this tool, Hanno collected a massive number of real-world keys from public sources, including Certificate Transparency logs, internet-wide TLS and SSH scans, PGP keys, and many others. By searching this dataset for unexpectedly sparse RSA moduli, we uncovered a large number of keys in the wild with the patterns in Figure 1...

The ordinary graphite in pencil lead is proving to be surprisingly multifaceted at the microscale. 

In a study appearing today in the journal Nature, MIT researchers report that a certain microscopic structure found in natural graphite can host multiple superconducting states. Superconductivity is an electronic state of matter in which electrons pair up and glide through a material with zero resistance. 

While there are thousands of materials that are known to be superconductors, it is rare for one material to host multiple forms of superconductivity. 

The researchers discovered the multiple superconducting states in atomically thin exfoliations of graphite, known as graphene. Specifically, graphene is a single-atom-thin sheet of carbon atoms arranged precisely in a microscopic lattice. The team made its discoveries in samples of rhombohedral graphene, which is a natural structure within graphite consisting of a stack of four or five graphene layers. 

Interestingly, the researchers found that several of the new superconducting states in rhombohedral graphene are able to persist in the presence of a magnetic field, which normally kills superconductivity. 

And in a further surprise, these superconducting states even get stronger when exposed to a magnetic field. 

Overall, the findings reveal a new family of unconventional superconducting states in one seemingly simple material. 

“People might assume that this is a simple, boring carbon material,” says Long Ju, the Lawrence C. and Sarah W. Biedenharn Associate Professor of Physics at MIT. “But we can control this material by tuning certain experimental ‘knobs,’ such as electrical voltages. This is how a simple physical material can exhibit so many different superconducting properties.” 

It’s still unclear exactly how each of the multiple superconducting states arise, or how they are able to persist under a magnetic field, when normally superconductivity should fade.

“From a fundamental physics point of view, it’s very exotic that a magnetic field doesn’t kill superconductivity, and instead it boosts it,” Ju says. “We have provided a lot of experimental results and provided the nutrition that people can absorb to try to think about what’s going on here.” 

The study’s MIT co-authors include co-first authors Junseok Seo and Shenyong Ye, together with Tonghang Han, Zhenghan Wu, Wei Xu, Jixiang Yang, Emily Aitken, Prayoga Liong, Phatthanon Pattanakanvijit, Zach Hadjri, and Mingda Li. External collaborators are co-first author Armel Cotten and members of Dominik Zumbuhl’s group at the University of Basel in Switzerland, plus others at Florida State University, the University of Florida, Gainesville, and the National Institute for Materials Science in Japan. 

Natural steps

Graphene and other atomically thin, two-dimensional materials can exhibit unexpected electronic, magnetic, thermal, and physical properties. And when two or more sheets of graphene are stacked and twisted at precise orientations, the “magic-angle” structure can suddenly host weird and exotic phenomena. 

Ju’s group has been probing the exceptional properties of graphene. But rather than artificially stacking and twisting layers, they have looked for interesting behavior in naturally occurring graphene structures. In recent years, they have unearthed surprising electronic properties in rhombohedral graphene. This particular configuration consists of graphene layers stacked on top of each other, each one slightly offset from the last, similar to the steps in a staircase. 

Rhombohedral graphene can be found naturally in ordinary graphite. But to find it first requires exfoliating a block of graphite (usually with Scotch tape), then searching the exfoliated sample for the telltale staircase-like pattern, which researchers can then isolate for further experimentation. 

Using this approach, Ju and his colleagues have been able to isolate and probe samples of four- and five-layer rhombohedral graphene. They have so far discovered that the structure can host a rare, “chiral” form of superconductivity, as well as fractional electron charge, among other behavior. 

In the flow

For their new study, the team took a slightly different approach in studying rhombohedral graphene. Previously, they electrically “doped” their samples, progressively adding electrons as they passed a separate electric current into the material. They then measured the voltage, or essentially the force that pushes the current through the material, and looked for instances when the voltage dropped to zero, indicating that the current was passing through without resistance.

In this way, the team has observed superconductivity when adding electrons to rhombohedral graphene. So they wondered: What might happen if they did the opposite, and took electrons away? 

In their new study, the team looked for signs of superconductivity as they carefully removed electrons from rhombohedral graphene, progressively lowering the material’s electron density, as they applied a separate, external electric current to measure the electrical resistance. In these experiments, they also applied external magnetic field along directions parallel and perpendicular to the graphene plane. These experiments were carried out in collaboration with Zumbuhl’s group in Switzerland, who provided access to a laboratory setup in which graphene samples could be exposed to high magnetic fields and ultracold temperatures. 

In these experiments, the researchers found that at certain electron densities, four different superconducting states emerged. What’s more, three of the states persisted in the presence of a relatively high magnetic field. 

Normally, magnets destroy superconductivity by severing the bond between the paired electrons gliding through the material. 

But in Ju’s experiments, the team observed three superconducting states that survived in a magnetic field up to around 9 tesla, which is about 180,000 times stronger than the Earth’s magnetic field. In these instances, the magnetic field they applied was in a parallel orientation with respect to the plane of the material. When they switched the magnetic field to a perpendicular orientation, they discovered another surprise: At a certain electron density, superconductivity not only persisted, but increased. The material was able to continue superconducting, at higher temperatures than predicted. 

Every superconducting material has a critical temperature below which electrons can conduct without resistance, and above which superconductivity cannot persist. But the team found that, at a certain electron density, and in the presence of a perpendicular magnetic field, superconductivity in rhombohedral graphene was able to survive beyond the material’s critical temperature that corresponds to zero magnetic field. 

“The superconductivity actually is enhanced, as in, the transition temperature goes from 55 millikelvin to probably 90 millikelvin,” Ju explains. “At the same time, the material can take another 50 or 60 percent extra current before superconductivity gets destroyed. And that is very unusual.”

The researchers are unsure of what microscopic behavior is enabling multiple and unconventional superconducting states, though they propose one idea. Conventional superconductivity emerges when electrons pair up. These “Cooper pairs” consist of electrons with opposite spin, and it’s thought that a magnetic field can pull the spins out of their opposite configurations, and as a result, break up superconductivity. 

Instead, the team proposes that perhaps in rhombohedral graphene, and at certain electron densities, electrons can pair up with aligned spins. Any magnetic field would still pull on the spins, but in the same direction, preserving their alignment, and their superconductivity. 

The researchers acknowledge that the idea needs much more investigation, both experimentally and theoretically. For now, they see the results as a demonstration of what new and exotic phenomena can emerge in a seemingly simple material, with the right measurements and controls. 

“We can control the simplest chemical and structural material— crystalline carbon— as part of the fun,” says lead author Junseok Seo, who is a graduate student in Ju’s group. “We’re not only dealing with what nature gives us, but we’re applying additional controls to change it to something that nature does not give us, but that can exist in the same material.”

We’ve taken one small step towards robot police officers: a drone capable of disarming a suspect:

In a June 22 video posted on the Sacramento County Sheriff’s Office’s Instagram page, an officer wearing goggles can be seen operating a drone to retrieve a knife from an armed suspect hiding inside a cluttered house. “After not responding to negotiators, a drone was deployed inside the residence,” the post says. “Drone pilots located the suspect hiding in a corner of a garage” and then used a high-powered magnet attached to the drone to grab the knife out of the suspect’s hand. In the video ­ which is soundtracked by the “Mission: Impossible” theme song—the intercepted knife can be seen spinning around in the air as the drone carries it back to the deputies...

This Pride month, we’re calling on the dating app Grindr to prioritize LGBTQ+ user safety by making privacy the default across its platform. That means no more sharing personal data with advertisers or training AI on private information without users’ opt-in consent.

Grindr is a dating app for the LGBTQ+ community; and for queer people, privacy violations can have life-altering consequences. Information that reveals someone’s sexual orientation, gender identity, or HIV status can be used by employers, governments, family members, scammers, or bad actors to inflict harassment, discrimination, arrest, or violence. For example, data from Grindr and other gay dating apps was sold by data brokers and used to 'out' (the act of disclosing someone's sexual orientation without permission) a gay priest in 2021. 

Despite being the world's most popular gay dating app, Grindr has repeatedly mishandled users' sensitive data. Grindr has been caught sharing users' HIV status and precise location with advertisers without obtaining valid consent, resulting in reprimands and fines in several countries. Its former Chief Privacy Officer even sued, alleging the company fired him for raising concerns about Grindr prioritizing “profit over privacy."

Grindr ended several of its most egregious data sharing practices after they were exposed. But more changes are needed if Grindr wants to earn back trust and prove its commitment to users’ privacy and safety. This Pride month, we’re calling on Grindr to make privacy the default and ensure the immediate implementation of two changes to better protect its users:

Opt Users Out of Behavioral Advertising by Default

Grindr currently allows users to opt out of behavioral advertising, but that protection is not enabled automatically (except in some unspecified regions). As we’ve long warned, behavioral advertising relies on the collection and sharing of personal data across a vast network of advertisers, intermediaries, and data brokers. Once information enters this ecosystem, users have little control over where it goes or how it is used: people’s most private and intimate information can be aggregated, sold, and combined with information from other sources to create detailed personal profiles.

By default, Grindr appears to share data with numerous advertising and tracking companies. Using TrackerControl, an app developed by privacy researcher Konrad Kollnig, we recorded Grindr contacting 20 third-party tracking domains during 15 minutes of app activity (see Grindr_TrackerControl_06-23-2026.csv for exported results). TrackerControl observed Grindr contacting Big Tech companies and ad-tech intermediaries, many of which have faced significant legal scrutiny for privacy violations. Several of these companies auction off ad space through a process called “real-time bidding,” which can expose user data to hundreds of additional companies and be exploited by data brokers. 

The dangers of Grindr’s default settings exposing users’ personal data to this ecosystem are not hypothetical. Between approximately 2017 to 2020, a location data broker collected the precise movements of millions of Grindr users from digital advertising networks and made them available for sale. The commercially available data was allegedly so detailed that, in some cases, it could be used to infer romantic encounters between specific Grindr users. 

Although Grindr has stated that it no longer shares precise location data or profile information with advertisers, it acknowledges sharing other personal data, including mobile advertising identifiers (MAIDs)—unique, persistent device IDs that allow advertising companies and data brokers to connect data about the same individual across different sources. MAIDs are not anonymous, and an entire industry exists to link them to more directly identifying information, like emails and phone numbers. According to Grindr’s privacy policy, companies receiving users’ MAIDs “are aware that such data is being transmitted from Grindr,” which could expose a users’ sexuality to the advertising and data broker ecosystem.

Opt Users Out of AI Training on Personal Data by Default

Grindr should stop training its AI models on users’ personal data without opt-in consent. 

Grindr has been investing heavily in AI features as its CEO strives to make Grindr an “AI-first business.” New AI features include a wingman chatbot, profile recommendations based on users’ inferred “type”, summaries of previous interactions with other users, and AI-generated insights about other profiles (like responsiveness, typical online hours, and engagement patterns). By default, Grindr uses its users’ personal data to train the AI models behind these features.

Grindr claims to never use sensitive health information for AI training and requires users to opt-in to AI training on “special-category” data, which includes chat content and precise location. But Grindr automatically enrolls users in AI training on other private information, including profile photos, age, taps, and display names. Users must navigate several levels of Grindr settings to prevent these personal details from being used to train Grindr’s AI.

AI systems trained on personal data create new privacy risks, including the possibility that personal information may be retained, reproduced, or exposed in unexpected ways. For example, researchers have been able to extract training data from AI systems like ChatGPT.

Beyond AI training, Grindr enables AI-powered features by default and allows both “special-category” data and other personal information to be processed by those features. Even users without access to premium-subscription AI features could have their data automatically used to power those features for other users. “Behavior-based profile insights” (pictured below) could expose information that users would never choose to share publicly, like the types of people they interact with on Grindr, their typical online hours, and how often they initiate conversation with other users.

Image of the “Profile Insights” feature from a Grindr blogpost promoting its premium, AI-first subscription

Regardless of whether new AI features leak private information, users deserve meaningful control over how their personal data is used and by whom. Grindr notifies users that their personal information may be used to train AI and that they can opt out on a separate settings page, but this notice does not specify the type of data used (i.e. profile photos, taps) and it is unlikely that people carefully read or understand it. Closing the notice or clicking its only button (which is “Proceed”) maintains Grindr’s default of using personal information for AI training. To respect users’ autonomy, Grindr should require opt-in consent before training AI models on personal data.

Celebrate Pride by Demanding Better Privacy

Grindr must immediately stop prioritizing profits over users’ safety. The ability to opt-out is not an acceptable substitute for opt-in consent, especially given the added risks of data sharing for LGBTQ+ users. Defaults matter—studies show that most people cannot or do not change the default settings of technologies they use.

If Grindr wants to back up its claim that it “takes user privacy very seriously,” it should make privacy the default across its platform, rather than something users need to go through complicated processes to opt in to. 

Poke your head into just about any online social network—or any general conversations about internet culture—and you’ll likely find a boogieman: the algorithm. Since at least the moment Facebook introduced (and apologized for) its News Feed, “the algorithm” has been shorthand for the ways the tech giants control what we see and when we see it. In the age of enshittification, there is a push to reclaim our feeds and networks. Good news: there’s a tool that’s been around for decades that can help wrangle many of your feeds into something manageable: Really Simple Syndication, more commonly known as RSS.

What’s RSS and How Do I Use It?

RSS has been around since 1999, but its real publicity glow-up came from Google Reader, a newsreader service that Google offered between 2005 and 2013. Despite the alarm bells people rang at the time, the death of Google Reader wasn’t the death of RSS, and many replacements have come and gone over the years.

RSS may seem complicated, but it boils down to one general concept: when websites publish new content, like news articles, blog entries, webcomics, videos, or podcasts, that content gets added to an RSS feed, where your RSS reader (aka newsreader, feed reader, or aggregator) will show you that content in chronological order. If you’ve ever used a podcast player like Apple Podcasts or Spotify to follow different podcasts, you’ve used RSS. You can think of it like an internet-wide “follow” button, where you can track the contents of websites, users, and more.

People talk about RSS like it’s a power user’s secret trick to making the internet more usable, but the real secret is that it’s not that hard to set up and use. Here’s what you need to do:

• Find an RSS reader: RSS readers come in many forms. Feedly, NewsBlur, or The Old Reader, are web-based, but have their own apps (though they also support third-party apps). Others, like NetNewsWire, are app-based, and support either using a web-based RSS reader like Feedly, or a local file. Some live in browsers or web extensions. There’s an abundance of choice in RSS readers, and part of the fun is finding one that best accomplishes what you want to do. But don’t worry about finding the right RSS reader right away. One of the many magic tricks of RSS is that it is platform agnostic, and nearly every RSS reader—whether it's a website or an app, supports importing and exporting a list of the sites you subscribe to. This means you can change RSS readers in a couple minutes. If you need some help finding an RSS reader, Wired, The Verge, and Privacy Guides all have useful roundups. 
• Collect your feeds: As for adding websites to your feeds, the process is straightforward. Most RSS readers are designed to help find the feed for a site for you, so you don’t need to go hunting down a special link. Just drop the URL of what you want to follow in your reader, and if an RSS feed exists, it should be able to find it. If not, some sites, including ours (and our current podcast, EFFector as well as our last series, How to Fix the Internet), provide direct links to our RSS feeds.
• Sort, filter, and build your feed: Adding a bunch of new feeds can be overwhelming, particularly for news sites. RSS readers typically include folders, which let you group similar feeds together and can be great for lifting up low-traffic updates you don’t want to miss. Your reader may also have different filters, like the option to block any article that contains “sponsored post.” 

RSS Is the Best Way to Follow the News

It can be very difficult to follow the news, whether that means politics, tech policy, or your hobbies. Solutions like Google News or Apple News have tried to make this simpler, but many find that their algorithmic feeds are as often a source of frustration and annoyance as they are genuinely useful. And no matter how often you tap on news stories that matter to you from publications you respect, there may always be stories that refuse to bubble up.

RSS can make reading the news much easier, reliable, and more private. The vast majority of news sites have RSS feeds you can subscribe to, and many, including CNN, The New York Times, BBC, Wired, Politico, and many others, offer RSS for specific sections or special feeds that include the full text of articles for subscribers, so you aren’t just pummeled with a firehose of news all day long (we’ll get to a tip below in the next section that tackles this problem if they don’t have separate feeds, though). In many cases, you can read articles right in your RSS reader, never being forced to engage with wonky comments sections or poor design choices on websites.

Of course, the news isn’t just general news sites, it also includes hobbyist or more niche sites, local news offerings, and blogs. Most of these sorts of websites also offer RSS feeds, as do newsletter platforms like Substack or Ghost. 

RSS Offers One Way to Fix Some Social Feeds

Decentralized social media like Mastodon, Bluesky, and Threads, use RSS for user feeds, so you can follow your friend’s posts on Bluesky or Mastodon without actually having an account on either. This can be especially helpful for news sources, too—where you likely wouldn’t want to subscribe to a feed of everything a national news organization publishes because that would include dozens if not hundreds of stories a day, you can instead subscribe to their social media posts, which often get you the most breaking or important news.

The internet is more than just Facebook.

Some legacy social media works with RSS, too, including YouTube, Reddit (though that is currently at risk), and Tumblr. But others, like Facebook, LinkedIn, and Instagram, wall off posts behind account requirements that seem to pop up if you simply look at an account page for too long, let alone come in from an RSS feed. These walled gardens prevent information from getting out there, which ranges from annoying, like when your favorite local brewery only posts their food truck schedule on Instagram, to dangerous, like when local public services only post to a Facebook page.

The internet is more than just Facebook. It’s more than Mastodon or Bluesky, too. It’s a decentralized smorgasbord of websites, tools, feeds, newsletters, social profiles, and more, and treating it as such will help us wrangle the information we want and trust. 

Other Surprising Places You’ll Find RSS Feeds

When in doubt, try copying and pasting the URL for a site into your RSS reader of choice, you might be surprised to find a feed that proves useful to you. Many places on the internet may offer RSS feeds without you even realizing it. For example, if you want to keep an eye on an artist’s prints that you like, but they don’t have Instagram where they usually post, you might be able to subscribe to their webstore, as some shopping platforms, like Big Cartel, create an RSS feed automatically. And for something even more tweakable, even Google Alerts can be turned into RSS feeds.

RSS is one of the best examples we have of the open web, where we can design and customize how we experience the internet, not the other way around.

If you prefer to track policy over products, then you’ll be happy to know that government sites often support RSS, including most U.S. government sites, many of which break them into different sections like the U.S. Department of State’s various feeds. Many local governments or other public services, like fire departments may offer the same. Some universities (and university newspapers) also sometimes offer some RSS feeds. 

And even if a website doesn’t have an RSS feed, there are workarounds from tools like RSSHub, RSS-Bridge, and RSS.app that require varying levels of technical expertise or a willingness to pay subscription fees.

RSS is one of the best examples we have of the open web, where we can design and customize how we experience the internet, not the other way around. RSS has come in and out of fashion, been declared dead, and has come back, every time. Open systems are the best way forward to a free, equitable internet, and the resilience and continued reinvention of RSS has shown just how creative the web community can be with open protocols.

David Autor, the Daniel (1972) and Gail Rubinfeld Professor in the MIT Department of Economics, has been named head of the Department of Economics, effective July 1.

“David is a world-class labor economist,” says Agustín Rayo, the Kenan Sahin Dean of the School of Humanities, Arts, and Social Sciences. “He is also an individual of wisdom and insight. I look forward to welcoming him to the school’s leadership team.”

Autor’s scholarship explores the labor-market impacts of technological change and globalization on job polarization, skill demands, earnings levels and inequality, and electoral outcomes. He serves as faculty co-director of the James M. and Cathleen D. Stone Center on Inequality and Shaping the Future of Work. 

“I’ve been at MIT since 1999, and I owe my career to the Institute, the department, and colleagues who are as kind as they are accomplished,” Autor says. “Stepping into this role is a chance to contribute to a place that has shaped me at every stage.”

Autor succeeds Jon Gruber, the Ford Professor of Economics, who has served as department head since July 2023.

Autor says he “aims to build on the stellar standard set by its faculty and students while navigating budget tightening and a shifting political landscape.” 

“Just as important, I want to lead the department toward the opportunities that advancing AI is opening in how we teach and what we research,” he adds.

Autor serves as co-director of the National Bureau of Economic Research (NBER) Labor Studies Program. He earned a BA in psychology from Tufts University in 1989 and a PhD in public policy from Harvard University’s Kennedy School of Government in 1999. 

Autor has received numerous awards for both his scholarship — the National Science Foundation CAREER Award, an Alfred P. Sloan Foundation Fellowship, the Sherwin Rosen Prize for outstanding contributions to the field of Labor Economics, the Andrew Carnegie Fellowship in 2019, the Society for Progress Medal in 2021 — and for his teaching, including the MIT MacVicar Faculty Fellowship, the James A. and Ruth Levitan Award for excellence in teaching, the Undergraduate Economic Association Teaching Award, and the Faculty Appreciation Award from the MIT Technology and Policy Program.

In 2020, Autor received the Heinz 25th Special Recognition Award from the Heinz Family Foundation for his work “transforming our understanding of how globalization and technological change are impacting jobs and earning prospects for American workers.” 

In 2023, Autor was one of two researchers across all scientific fields who was named a NOMIS Distinguished Scientist. 

In 2024, Autor was one of five senior scholars selected by the Schmidt Sciences Foundation as an AI2050 Senior Fellow.

This is not science fiction. It’s not premature. If towns, cities, states, or the federal government want to act to reign in the emergence of armed police drones and robots, we have precious little time. In the absence of substantial regulation around when and how domestic law enforcement in the United States can deploy force using drones, the companies that markets technology to law enforcement have been moving. It’s past time concerned people take notice. Cities should not procure weaponized drones or robots, and multi-purpose drones and robots should be restricted from causing harm. 

Since 2021, EFF has been advocating against the use of armed robots or drones by law enforcement. This call has become more urgent as companies are moving in to take advantage of the lax regulatory landscape.

This month, two disturbing developments raised concerns that we might be on the verge of a larger trend of drone militarization. The first is that the CEO of Skydio, one of the most prolific vendors of police drones in the United States, signaled that the company has a more permissive attitude toward arming their drones in some contexts than many people expected. When asked on a podcast about the public perception that the company had restrictions around letting the military arm their drones, CEO Adam Bry said, “This is an area where I’ve gotten some things wrong. We said some things previously that led folks externally and internally to believe that, for example, we would prevent the military from putting weapons on our drones […] It’s very easy to sit back in a Silicon Valley office and think that we’re very smart, that we know the technology, and the idea of using it for X, Y, or Z thing seems evil or bad, so we’re going to write a policy or ban people from doing it. I think that’s ultimately misguided.”

Simply put: he is signaling that Skydio will not implement restrictions on their customers’ use of their devices. 

Bry was specifically asked about the military arming drones but the question reveals a disturbing truth: whether police arm drones domestically is currently based more on the internal ethical commitments of companies than it is any laws created by elected officials. Combining Skydio’s huge amount of police contracts, including supplying entire fleets for Drone as First Responders (DFR) programs, and the tendency of military technologies like surveillance aerostats to get redeployed on U.S. soil, creates a real recipe for the emergence of armed police drones. 

The other piece on the chess board to keep our eye on is the introduction of weaponized drones as a tool of school safety. A company called Campus Guardian Angel will run pilot programs in schools in Georgia and Florida in Fall 2026 to introduce drones that are designed to swarm, distract, crash into, and even shoot irritants at potential school shooters. This comes just years after a large national backlash that got the large police tech company Axon to pause its development of drones armed with tasers as a solution to school shootings. 

Although it may be obvious to some people, it’s worth saying again: antagonizing an active shooter with a small drone is a dangerous idea. In chaotic situations, deploying physical harm via drone is likely to get bystanders or good samaritans hurt by accident. It is also unproven that this technology will work to distract or deter an actual school shooter–especially when the demonstrations we see online revolve around crashing drones into stationary mannequins in pristine, controlled conditions. Another important question: What would happen if a potential shooter shoots at the small moving drone and endangers the people fleeing behind it? After all, in the demonstrations we’ve seen it is unclear if these drones have the ability to see what is behind them.  This is an unproven and potentially dangerous method of combating the very serious problem of gun violence in schools, and it’s one that helps to normalize armed drones as a solution to other policing problems as well. 

These developments also mean It’s not enough to follow San Francisco’s lead, which became the first city to change its policy regarding how robots could be used in order to ban police from using deadly force via robots in 2022. A robust and effective policy must include both drones and robots (not one or the other), and it has to explicitly prevent drones and robots from deploying any body harm — including deadly force and less-lethal measures like kinetic strikes, pepper spray, rubber bullets, or tasers. In addition, cities and states should not procure weaponized drones and robots. 

Since 2021, EFF has been advocating against the use of armed robots or drones by law enforcement. This call has become more urgent as companies are moving in to take advantage of the lax regulatory landscape. We cannot continue to rely solely on the good will of companies that make their money selling technology to police departments to protect us from dangerous police technology. Lawmakers need to act now. 

Ignoring EFF’s warnings about the dangers and impossibility of implementing a new mandate for 3D print surveillance software, the California State Assembly has signed off on legislation to do just that. In the process, legislators amended the bill to make it even more confusing, while failing to address the risks to privacy, speech, and consumer rights. We must renew our call on legislators to drop this bill as it heads to the state senate, and protect the tools of creators in the state.

What’s changed about the bill?

Since we first wrote about AB  2047, a bill targeting 3D printers for the rare, impractical, and already outlawed practice of manufacturing firearms without a license, it has picked up several amendments. Some are welcome changes, but most have only highlighted the technocratic absurdity of the proposed scheme. Our core concerns—that this mandate censors lawful speech, builds out corporate surveillance, and criminalizes open source experimentation—have not been remedied. 

Removes criminalization of resale

Starting with one silver lining, the current bill includes a carveout for the private resale of devices. The original bill would have made it a criminal offense for an individual to resell 3D printers purchased before this mandated censorship and surveillance software. This is a clear win for the 3D-printing community, but it is unfortunately not enough.

Ineffective carveouts for open source

One of the most dangerous aspects of the bill is that it criminalizes individual users for common practices, like creating and using alternative open source programs with their 3D printer. New amendments provide a carveout for the use of an open source tool, but only if it includes compliant censorship software. The bill burdens open source developers with ambiguous and unrealistic standards for print blocking, and continues to create a chilling effect for open source users.

Removes any actual requirement to work

To reiterate—there is no world where the mandated technology actually works as intended. It will both block lawful use of 3D printers, and allow firearms to be printed by anyone determined to do so. There is no amendment that can change this reality.

Instead, the current bill simply drops the pretense that this mandate is expected to work. The performance standard of algorithms changed from “effectively prevent[ing] a technically skilled user from evading [the algorithm]” to “substantially reduce the likelihood of foreseeable circumvention attempts…” The bill will still require all prints to be surveilled, but instead of testing efficacy against a skilled user, it just plays whack-a-mole with the (literally) infinite number of circumventions that any user can employ. 

Further, the bill now leaves us with an unclear process that relies on non-governmental third parties to define standards, and now relies on manufacturers and resellers to self-police.

Hollywood gets a cut

The bill includes yet another carve out for commercial users. This time for the entertainment industry, which makes extensive use of 3D printers for props and costumes. 

That’s fine for big studios, but it leaves out indie filmmakers, cosplayers, and many other small creators. 

This is simply a defensive edit to limit corporate opposition. There isn’t a clear division in 3D-printing between consumer and commercial tools. These are general purpose tools which might be picked up by a prop department of a big studio, or an artist getting ready for Comic Con. Indeed consumer level products are not only used by amateur artists and engineers developing their skills. Commercial 3D printers, like their traditional 2D equivalents, are frequently used in workplaces, as well as by professionals honing their skills or just trying to get some work done at home. 

Commercial carveouts hands printer manufacturers the ability to sell a more expensive tier of printers, locking-in and up-charging their commercial customers. Some of those customers will choose to buy general retail versions, but that carries its own price: increased risk of IP theft as all printed files are surveilled the same way they are for hobbyists. That means a real risk of businesses leaking any prototypes or new designs to not only the printer manufacturer, but potentially snooping governments and/or the general public through data breaches.

Demand  your senator oppose AB 2047

This updated version of AB 2047 downgrades performance standards and removes oversight while still threatening privacy and choice for users of 3D printers. A printer surveillance system won’t work for its intended purpose, and will only harm law abiding users. 

Act now to demand your senators to vote no on this ineffective and invasive bill.
