Transistors, the building blocks of modern electronics, are typically made of silicon. Because it’s a semiconductor, this material can control the flow of electricity in a circuit. But silicon has fundamental physical limits that restrict how compact and energy-efficient a transistor can be.

MIT researchers have now replaced silicon with a magnetic semiconductor, creating a magnetic transistor that could enable smaller, faster, and more energy-efficient circuits. The material’s magnetism strongly influences its electronic behavior, leading to more efficient control of the flow of electricity. 

The team used a novel magnetic material and an optimization process that reduces the material’s defects, which boosts the transistor’s performance.

The material’s unique magnetic properties also allow for transistors with built-in memory, which would simplify circuit design and unlock new applications for high-performance electronics.

“People have known about magnets for thousands of years, but there are very limited ways to incorporate magnetism into electronics. We have shown a new way to efficiently utilize magnetism that opens up a lot of possibilities for future applications and research,” says Chung-Tao Chou, an MIT graduate student in the departments of Electrical Engineering and Computer Science (EECS) and Physics, and co-lead author of a paper on this advance.

Chou is joined on the paper by co-lead author Eugene Park, a graduate student in the Department of Materials Science and Engineering (DMSE); Julian Klein, a DMSE research scientist; Josep Ingla-Aynes, a postdoc in the MIT Plasma Science and Fusion Center; Jagadeesh S. Moodera, a senior research scientist in the Department of Physics; and senior authors Frances Ross, TDK Professor in DMSE; and Luqiao Liu, an associate professor in EECS, and a member of the Research Laboratory of Electronics; as well as others at the University of Chemistry and Technology in Prague. The paper appears today in Physical Review Letters.

Overcoming the limits

In an electronic device, silicon semiconductor transistors act like tiny light switches that turn a circuit on and off, or amplify weak signals in a communication system. They do this using a small input voltage.

But a fundamental physical limit of silicon semiconductors prevents a transistor from operating below a certain voltage, which hinders its energy efficiency.

To make more efficient electronics, researchers have spent decades working toward magnetic transistors that utilize electron spin to control the flow of electricity. Electron spin is a fundamental property that enables electrons to behave like tiny magnets.

So far, scientists have mostly been limited to using certain magnetic materials. These lack the favorable electronic properties of semiconductors, constraining device performance.

“In this work, we combine magnetism and semiconductor physics to realize useful spintronic devices,” Liu says.

The researchers replace the silicon in the surface layer of a transistor with chromium sulfur bromide, a two-dimensional material that acts as a magnetic semiconductor.

Due to the material’s structure, researchers can switch between two magnetic states very cleanly. This makes it ideal for use in a transistor that smoothly switches between “on” and “off.”

“One of the biggest challenges we faced was finding the right material. We tried many other materials that didn’t work,” Chou says.

They discovered that changing these magnetic states modifies the material’s electronic properties, enabling low-energy operation. And unlike many other 2D materials, chromium sulfur bromide remains stable in air.

To make a transistor, the researchers pattern electrodes onto a silicon substrate, then carefully align and transfer the 2D material on top. They use tape to pick up a tiny piece of material, only a few tens of nanometers thick, and place it onto the substrate.

“A lot of researchers will use solvents or glue to do the transfer, but transistors require a very clean surface. We eliminate all those risks by simplifying this step,” Chou says.

Leveraging magnetism

This lack of contamination enables their device to outperform existing magnetic transistors. Most others can only create a weak magnetic effect, changing the flow of current by a few percent or less. Their new transistor can switch or amplify the electric current by a factor of 10.

They use an external magnetic field to change the magnetic state of the material, switching the transistor using significantly less energy than would usually be required.

The material also allows them to control the magnetic states with electric current. This is important because engineers cannot apply magnetic fields to individual transistors in an electronic device. They need to control each one electrically.

The material’s magnetic properties could also enable transistors with built-in memory, simplifying the design of logic or memory circuits.

A typical memory device has a magnetic cell to store information and a transistor to read it out. Their method can combine both into one magnetic transistor.

“Now, not only are transistors turning on and off, they are also remembering information. And because we can switch the transistor with greater magnitude, the signal is much stronger so we can read out the information faster, and in a much more reliable way,” Liu says.

Building on this demonstration, the researchers plan to further study the use of electrical current to control the device. They are also working to make their method scalable so they can fabricate arrays of transistors.

This research was supported, in part, by the Semiconductor Research Corporation, the U.S. Defense Advanced Research Projects Agency (DARPA), the U.S. National Science Foundation (NSF), the U.S. Department of Energy, the U.S. Army Research Office, and the Czech Ministry of Education, Youth, and Sports. The work was partially carried out at the MIT.nano facilities.

For the last hundred years, women have had pivotal and far too often unsung roles in building and shaping the technology that we now use every day. Many have heard of Ada Lovelace’s contributions to computer programming, but far fewer know Mary Allen Wilkes, a prominent modern programmer who wrote much of the software for the LINC, one of the world’s first interactive personal computers (it could fit in a single office and cost $40,000, but it was the 60’s). Decades earlier, when the first all-electronic, digital Eniac computer was built in the 40’s, the “software” for it was written by women: Kathleen McNulty, Jean Jennings, Betty Snyder, Marlyn Wescoff, Frances Bilas and Ruth Lichterman. 

It’s thankfully become more common knowledge that actor and inventor Hedy Lamarr co-created the concept of "frequency-hopping" that became a basis for radio systems from cell phones to wireless networking systems. But too few know Laila Ohlgren, who in the 1970’s solved a major problem with the development of mobile networks and phones by recognizing that dialed numbers could be stored and sent all at once with a “call button,” rather than sent one number at a time, which created connection issues before a call was even made. 

Women in tech deserve more and brighter spotlights. At EFF, we’ve had the honor of celebrating some of our heroes at our annual EFF Awards, including many women who are leading the digital rights community. For International Women’s Day, we’re highlighting the contributions of just a few of these recipients from the last decade, whose work to protect privacy, speech, and creativity online has had a global impact.

Carolina Botero (EFF Award Winner, 2024) 

Carolina Botero is a leader in the fight for digital rights in Latin America. For over a decade, she led the Colombia-based Karisma Foundation and cultivated its regional and international impact. Botero and Karisma helped connect indigenous peoples to the internet and made it possible to contribute content to Wikipedia in their native language, expanding access to both history and modern information. They built alliances to combat disinformation, pushed for legal tools to protect cultural and heritage institutions from digital blackholes, and were, and remain, a necessary voice speaking for human rights in the online world. EFF worked closely with Karisma and Botero to help free Colombian graduate student Diego Gomez, who shared another student’s Master’s thesis with colleagues over the internet. Diego’s story demonstrates what can go wrong when nations enact severe penalties for copyright infringement, and thanks to work from Karisma, many partners, and many EFF supporters, he was cleared of the criminal charges that he faced for this harmless act of sharing scholarly research.

Carolina Botero receiving her EFF Award

Botero stepped down from the role in 2024, opening the door for a new generation. While her work continues—she’s currently on the advisory board of CELE, the Centro de Estudios en Libertad de Expresión—her EFF Award was well-deserved based on her strong and inspiring legacy for those in Latin America and beyond who advocate for a digital world that enhances rights and empowers the powerless. Learn more about Botero on her EFF Awards page and the recap of the 2024 event. 

Chelsea Manning (EFF Award Winner, 2017)

Chelsea Manning became famous as a whistleblower: In 2010, she disclosed classified Iraq War documents, including a video of the killings of Iraqi civilians and two Reuters reporters by U.S. troops. These documents exposed aspects of U.S. operations in Iraq and Afghanistan that infuriated the public and embarrassed the government. But she is also a transparency and transgender rights advocate, network security expert, author, and former U.S. Army intelligence analyst. 

Manning joined the military in 2007. Her role as an intelligence analyst to an Army unit in Iraq in 2009 gave her access to classified databases, but more importantly, it gave her a uniquely comprehensive view of the war in Iraq, and she became increasingly disillusioned and frustrated by what she saw, versus what was being shared. In 2010, she approached major news outlets hoping to give information to them that would reveal a new side of the war to the public. Ultimately, she shared the documents with Wikileaks. 

Manning’s bravery did not end there. When she was arrested a few months later, she endured "cruel, inhuman and degrading" treatment, according to the UN Special Rapporteur on torture. She was locked up alone for 23 hours a day over an 11-month period, before her trial. The mistreatment resulted in public outcry and advocacy by organizations like Amnesty International. Even a State Department spokesperson, Philip Crowley, criticized the treatment as "ridiculous, counterproductive, and stupid," and resigned. She was moved to a medium-security facility in April 2011. 

The government’s charges against Manning were outrageous, but in 2013 she was convicted of 19 of 22 counts as a result of her whistleblowing activities. She became one of fewerthan a dozen people prosecuted for espionage in the entire history of the United States, and she was sentenced to the longest punishment ever imposed on a whistleblower. Then, the day after her conviction, isolated from her community and in all likelihood expecting to remain in prison for years if not decades, she courageously issued a statement identifying herself as a trans woman, which she’d wanted to reveal for years. 

Over the next several years, while imprisoned, she became an advocate both for government transparency and for transgender rights. Her conviction and sentence pointed to the need for legal reform of both the Computer Fraud and Abuse Act (CFAA) and the Espionage Act.  EFF filed an amicus brief to the U.S. Army Court of Criminal Appeals arguing that the CFAA was never meant to criminalize violations of private policies like those of government systems, and EFF also pushed, and continues to fight for, narrower interpretations of the Espionage Act and stronger protections for whistleblowers, particularly to take into account both the motivation of individuals who pass on documents and the disclosure’s ramifications. 

Even after President Obama commuted her sentence in 2017, and EFF celebrated her work and her release with an EFF award in September, 2017, her fight wasn’t over. She was imprisoned again twice in 2019 and ultimately fined $256,000 for refusing to testify before grand juries investigating WikiLeaks founder Julian Assange. The U.N. Special Rapporteur on torture again criticized Manning’s treatment, writing that "the practice of coercive detention appears to be incompatible with the international human rights obligations of the United States." 

Manning was released in 2020 after having spent almost a decade in total imprisoned for her courage. She wrote a memoir, README.txt, in 2022, to take back control over her story.

EFF Award Winners Mike Masnick, Annie Game, and Chelsea Manning

Annie Game (EFF Award Winner, 2017)

Annie Game spent over 16 years as the Executive Director of IFEX, a global network of journalism and civil liberties organizations working together to defend freedom of expression.  IFEX (formerly International Freedom of Expression Exchange) began in the 1990s, when a group of organizations and the Canadian Committee to Protect Journalists came together to consider how to respond as a single voice to free-expression violations around the world. IFEX now is a global hub for the protection of free speech and journalism. 

Game recognized early on that digital rights and freedom of expression groups needed one another. Under her leadership, IFEX paired more traditional free-expression organizations with their more digital counterparts, with a focus on building organizational security capacities. IFEX Initiatives under Game’s leadership have been expansive. For example, the International Day to End Impunity for Crimes against Journalists, November 2, has been an annual wake-up call and reminder for UN member states to live up to their commitments to protecting journalists. UNESCO observed more than 1,700 journalists were killed globally between 2006 and 2024, and nearly 90% of these cases went unsolved in the courts. 

Game and IFEX have also focused on high-profile cases of journalists threatened by governments for their work, such as Bahey eldin Hassan in Egypt. Bahey is the director of the Cairo Institute for Human Rights Studies (CIHRS) and has advocated for freedom of expression and the basic human rights of Egyptians, but has lived in exile since 2014. The charges against him, of “disseminating false information” and “insulting the judiciary,” are common tactics of intimidation and harassment. Bahey’s supposed crimes were sharing social media posts criticising the Egyptian judiciary’s lack of independence, and speaking about the killing in Egypt of Italian researcher Giulio Regeni. Bahey—an IFEX member—is just one of many reporters and human rights workers in danger when they speak. But when journalists and those defending their rights online speak out as one voice, as IFEX helps them do, it makes a difference. 

Another initiative has been the Faces of Free Expression project, a partnership between IFEX and the International Free Expression Project. If you’re looking for more heroes, this project details the stories of “risk-takers and change-makers – individuals who put their careers, their freedom, their safety, and sometimes even their lives on the line,” while reporting, or defending free expression and the right to information. 

Wherever authoritarianism and repression of speech have been on the rise, Game has unapologetically called out injustices and made it safer for journalists to do their work, while ensuring accountability when crimes are committed. The work is more critical now than ever, and since leaving IFEX in 2022, she’s remained an activist while focusing increasingly on environmental protection.

In honor of International Women’s Day, we asked five women at EFF about women in digital rights, freedom of expression, technology, and tech activism who have inspired us.  

Anna Politkovskaya 

Jillian York, Activist 
This International Women’s Day, I want to honor the memory of Anna Politkovskaya, the Russian investigative journalist who relentlessly exposed political and social abuses, endured harassment and violence for her work, and was ultimately killed for telling the truth. I had just started my career when I learned of her death, and it forced me to confront that freedom of expression isn’t an abstract principle but rather something people risk—and sometimes lose—their lives for. 

Her story reminds me that journalism at its best is an act of moral courage, not just a profession. In the face of threats, poison, and relentless pressure to stay silent, she chose to continue writing about what she saw, insisting that ordinary people’s lives were worth the world’s attention. She refused to compromise with power, even when she knew it could cost her life. To me, defending freedom of expression means defending those like Anna who bear witness to injustice, prioritize truth, and hold power to account for those whose voices are silenced.  

Cindy Cohn 

Corynne McSherry, Legal Director 
There are so many women who have shaped tech history–most of whom are still unsung heroes—that it’s hard to single out just one. But it’s easier this year because it’s a chance to celebrate my boss, Cindy Cohn, before she leaves EFF for her next adventure.  

Cindy has been fighting for our digital rights for 30 years. leading EFF’s legal work and eventually the whole organization. She helped courts understand that code is speech deserving of constitutional protections at a time when many judges weren’t entirely sure what code even was. She led the fight against NSA spying, and even though outdated and ill-fitting doctrines like the state secrets privilege prevented courts from ruling on the obvious unconstitutionality of the NSA’s mass surveillance program, the fight itself led to real reforms that have expanded over time.   

I’ve worked closely with her for much of her EFF career, starting in 2005 when we sued Sony for installing spyware in millions of computers, and I’ve seen firsthand her work as a visionary lawyer, outstanding writer, and tireless champion for user privacy, free expression, and innovation. She’s also warm and funny, with the biggest heart in the world, and I’m proud to call her a friend as well as a mentor.  

Jane

Sarah Hamid, Activist 
When talking about women in tech, we usually mean founders, engineers, and executives. But just as important are the women who quietly built the practices that underpin today’s movement security culture. 

For as long as social movements have organized in the shadow of state surveillance, women have been designing the protocols, mutual aid networks, and information flows that keep people alive. Those threats feel ever-escalating: fusion‑center monitoring of protests, federal agencies infiltrating and subpoenaing encrypted Signal and social media chats, prosecutors mining search histories.  

In the late 1960s and early 1970s, the underground Jane abortion counseling service—formally the Abortion Counseling Service of Women’s Liberation—built what we would now recognize as a feminist infosec project for abortion access. Jane connected an estimated 11,000 people with safer abortions before Roe v. Wade, using a single public phone number—“Call Jane”—paired with code names, compartmentalized roles, and minimal records so no one person held the full story of who needed care, who was providing it, and where. When Chicago police raided the collective in 1972, members destroyed their index‑card files rather than let them become a ready‑made map of patients and helpers—an analog secure‑deletion choice that should feel familiar to anyone who has ever wiped a phone or locked down a shared drive. 

The lesson we should take from Jane is a set of principles that still hold in our encrypted‑but‑insecure present: Collect less, separate what you do collect, and be ready to burn the file box. When a search query, a location ping, or a solidarity post can become evidence, treating information as both lifeline and liability is not paranoia—it is care work.  

Ebele Okobi

Babette Ngene, Director of Public Interest Technology 
In the winter of 2013, I had just landed my first job at the intersection of tech and human rights, working for a prominent nonprofit and I was encouraged to attend regular tech and policy events around town. One such event on internet governance was happening at George Washington Universit,  focusing on multistakeholder engagement on internet policy and governance issues, with companies, nonprofits, and government representatives in attendance. I was inexperienced with these topics, and I’ll admit I was a bit intimidated. 

Then I saw her. She was the only woman on the opening panel, an African woman, an accomplished woman. Not only was she a respected lawyer at Yahoo at the time, but her impressive background, presence, and confident speaking style immediately inspired me. She made me feel like I, too, belonged in that room and could become a powerful voice. 

Ebele Okobi would go on to become one of the most powerful and respected voices in the tech and human rights space, known for her advocacy for digital rights and responsible innovation across Africa and the broader global majority during her tenure at Facebook. Beyond her corporate advocacy, Ebele has consistently championed ethical technology and social justice. She embodies the leadership qualities I value most: empathy, speaking truth to power, integrity, and authenticity. 

I remain in the tech and human rights space because I saw her, because seeing her made me feel seen. Representation truly does matter.  

Ada Lovelace 

Allison Morris, Chief Development Director 
I’m not a lawyer, activist, or technologist; I’m a fundraiser and a lover of stories. And what storyteller at EFF couldn’t help but love Ada Lovelace? The daughter of Lord Byron – the human embodiment of Romanticism – Ada was an innovator in math and science and, ultimately, the writer of the first computer program.  

Lovelace saw the potential in Charles Babbage’s theoretical General Purpose Computer (which was never actually built) and created the foundations of modern computing long before the digital age. In creating the first computer code, Lovelace took Babbage’s concept of a machine that could perform mathematical calculations and realized that it could manipulate symbols as well as numbers. 

Given the expectations of women in her time and the controversy of what work should be attributed to Lovelace as opposed to the man she often worked with, I can’t help but be inspired by her story.

For as long as social movements have organized in the shadow of state surveillance, women have been designing the protocols, mutual aid networks, and information flows that keep people alive. Those threats feel ever-escalating: fusion‑center monitoring of protests, federal agencies infiltrating and subpoenaing encrypted Signal and social media chats, prosecutors mining search histories.  

In the late 1960s and early 1970s, the underground Jane abortion counseling service—formally the Abortion Counseling Service of Women’s Liberation—built what we would now recognize as a feminist infosec project for abortion access. Jane connected an estimated 11,000 people with safer abortions before Roe v. Wade, using a single public phone number—“Call Jane”—paired with code names, compartmentalized roles, and minimal records so no one person held the full story of who needed care, who was providing it, and where. When Chicago police raided the collective in 1972, members destroyed their index‑card files rather than let them become a ready‑made map of patients and helpers—an analog secure‑deletion choice that should feel familiar to anyone who has ever wiped a phone or locked down a shared drive. 

The lesson we should take from Jane is a set of principles that still hold in our encrypted‑but‑insecure present: Collect less, separate what you do collect, and be ready to burn the file box. When a search query, a location ping, or a solidarity post can become evidence, treating information as both lifeline and liability is not paranoia—it is care work.  

Ebele Okobi

Babette Ngene, Director of Public Interest Technology 
In the winter of 2013, I had just landed my first job at the intersection of tech and human rights, working for a prominent nonprofit and I was encouraged to attend regular tech and policy events around town. One such event on internet governance was happening at George Washington Universit,  focusing on multistakeholder engagement on internet policy and governance issues, with companies, nonprofits, and government representatives in attendance. I was inexperienced with these topics, and I’ll admit I was a bit intimidated. 

Then I saw her. She was the only woman on the opening panel, an African woman, an accomplished woman. Not only was she a respected lawyer at Yahoo at the time, but her impressive background, presence, and confident speaking style immediately inspired me. She made me feel like I, too, belonged in that room and could become a powerful voice. 

Ebele Okobi would go on to become one of the most powerful and respected voices in the tech and human rights space, known for her advocacy for digital rights and responsible innovation across Africa and the broader global majority during her tenure at Facebook. Beyond her corporate advocacy, Ebele has consistently championed ethical technology and social justice. She embodies the leadership qualities I value most: empathy, speaking truth to power, integrity, and authenticity. 

I remain in the tech and human rights space because I saw her, because seeing her made me feel seen. Representation truly does matter.  

Ada Lovelace 

Allison Morris, Chief Development Director 
I’m not a lawyer, activist, or technologist; I’m a fundraiser and a lover of stories. And what storyteller at EFF couldn’t help but love Ada Lovelace? The daughter of Lord Byron – the human embodiment of Romanticism – Ada was an innovator in math and science and, ultimately, the writer of the first computer program.  

Lovelace saw the potential in Charles Babbage’s theoretical General Purpose Computer (which was never actually built) and created the foundations of modern computing long before the digital age. In creating the first computer code, Lovelace took Babbage’s concept of a machine that could perform mathematical calculations and realized that it could manipulate symbols as well as numbers. 

Given the expectations of women in her time and the controversy of what work should be attributed to Lovelace as opposed to the man she often worked with, I can’t help but be inspired by her story.

Women in tech deserve more and brighter spotlights. At EFF, we’ve had the honor of celebrating some of our heroes at our annual EFF Awards, including many women who are leading the digital rights community. For International Women’s Day, we also highlighted the contributions of just a few of these recipients from the last decade, whose work to protect privacy, speech, and creativity online has had a global impact.

This is a very weird story about how squid stayed on the menu of Byzantine monks by falling between the cracks of dietary rules.

At Constantinople’s Monastery of Stoudios, the kitchen didn’t answer to appetite.

It answered to the “typikon”: a manual for ensuring that nothing unexpected happened at mealtimes. Meat: forbidden. Dairy: forbidden. Eggs: forbidden. Fish: feast-day only. Oil: regulated. But squid?

Squid had eight arms, no bones, and a gift for changing color. Nobody had bothered writing a regulation for that. This wasn’t a loophole born of legal creativity but an oversight rooted in taxonomic confusion. Medieval monks, confronted with a creature that was neither fish nor fowl, gave up and let it pass...

Social psychologist Jonathan Haidt presented a forceful analysis of the damage smartphones and social media are doing to our cognition, our civic fabric, and our children’s wellbeing, while calling for renewed action to ward off their effects, in the latest of MIT’s Compton Lectures on Wednesday.

“Around the world, people are getting diminished,” Haidt said. “Less intelligent, less happy, less competent. And it’s happening very fast … My argument is that if we continue with current trends as AI is coming in, it’s going to accelerate. The decline of humanity is going to accelerate.”

Haidt is the Thomas Cooley Professor of Ethical Leadership at New York University’s Stern School of Business and the author of the recent bestseller “The Anxious Generation,” which suggests that the widespread adoption of social media in the 2010s has been especially damaging to young women, making them prone to anxiety and depression.

But as Haidt has continued to examine the effects of social media on society, he has started focusing on additional issues. Our inability to put our phones away, our compulsion to check social media, and the way we spend hours a day watching short-form videos, may be causing problems that go far beyond any rise in anxiety and depression.

“It turns out, it’s not the biggest thing,” Haidt said. “There’s something bigger. It is the destruction of the human capacity to pay attention. Because this is affecting most people, including most adults. And if you imagine humanity with 10 to 50 percent of its attentional ability sucked out of it, there’s not much left. We’re not very capable of doing things if we can’t focus or stay on a task for more than 30 seconds.”

Whatever solution may emerge to these problems, Haidt declared, is going to have to come from “human agency. People see a problem, they figure out a way around it. That’s what I’m hoping to promote here [to] this very important audience. So please consider what I’m saying, these trends, and then work to change them.”

Haidt’s lecture, titled, “Life After Babel: Democracy and Human Development in the Fractured, Lonely World That Technology Gave Us,” was delivered before a capacity audience of over 400 people in MIT’s Huntington Hall (Room 10-250).

The lecture spanned a variety of related topics, with Haidt presenting chart after chart showing the onset of declines in cognition, educational achievement, and happiness, which all have seemed to occur soon after the widespread adoption of smartphones in the 2010s. The individual adoption of smartphones, he notes, has been compounded by the way schools brought internet-connected computing devices into classrooms around the same time.

“The biggest, the most costly mistake we’ve ever made in the history of American education [was] to put computers and high tech on people’s desks,” Haidt said.

Distractible students with shorter attention spans are reading fewer books, he noted; some cinema students cannot sit through films. The top quartile of students is continuing to do well, he noted, but for most students, proficiency levels have dipped notably since the 2010s.

“Fifty years of progress in education, 50 years of progress, up in smoke, gone,” Haidt said. “We’re back to where we were 50 years ago. That’s pretty big, that’s pretty serious.”

As Haidt mentioned multiple times in his remarks, he is not an opponent of all forms of technology, or even personal communication technology, but rather is seeking to mitigate its harmful effects.

“I love tech, I love modernity, we’re all dependent on it, I love my iPhone,” Haidt said. Just as he finished that sentence, an audience member’s cellphone started ringing loudly — drawing a huge laugh from the audience.

“I did not plant that, that was a truly spontaneous demonstration of what I’m talking about,” Haidt said.

Haidt was introduced by MIT President Sally A. Kornbluth, who called him “a leading voice for reforming society’s relationship with technology.” She praised Haidt’s work, noting that he wants to “encourage us to imagine a more positive role for technology in humanity’s future.”

The Karl Taylor Compton Lecture Series was introduced in 1957. It is named for MIT’s ninth president, who led the Institute from 1930 to 1948 and also served as chair of the MIT Corporation from 1948 to 1954.

Compton, as Kornbluth observed, helped MIT evolve from being more strictly an engineering school into “a great global university” with “a new focus on fundamental scientific research.” During World War II, she added, Compton “helped invent the longstanding partnership between the federal government and America’s research universities.”

Haidt received his undergraduate degree from Yale University and his PhD from the University of Pennsylvania. He taught on the faculty at the University of Virginia for 16 years before joining New York University. He has written several widely discussed books about contemporary civic life. Haidt observed that the problems stemming from device distraction and compulsion appear to have hit so-called Gen Z — those born from roughly the mid 1990s to the early 2010s — especially hard, though he emphasized that people in that cohort are essentially victims of circumstance.

“I am not blaming Gen Z,” Haidt said. “I am saying we raised our kids in a way — we allowed the technology companies to take over childhood. We allowed a few giant companies to own our children’s attention, to show them millions of short videos, to destroy their ability to pay attention, to stop them from reading books, and this is the result.”

For a portion of his remarks, Haidt also examined the consequences of social media for politics, showing data that chart the global diminishment of democracy since the 2010s, while the world has become soaked in misinformation and conflictual online interactions.

“That, I think, is what digital technology has done to us,” Haidt said. “It was supposed to connect us, but instead it has broken things, divided us, and made it very, very hard to ever have common facts, common truths, common stories again.”

Towards the end of his remarks, Haidt also speculated that the effects of using AI will be corrosive as well, intellectually and psychologically.

“AI is not exactly going to make us better at interacting with human beings,” Haidt said.

With all this in mind, what is to be done, to limit the intellectual and social damage from tech devices and social media? For one thing, Haidt suggested, we should be less impressed by high-tech innovations and social media.

“We need to disenthrall ourselves from technology,” Haidt said, paraphrasing a line written by President Abraham Lincoln. He added: “I suggest that we have a generally negative view … of social media and of AI.” This kind of “more emotionally negative or ambivalent view” will make it easier for us to reverse the way technology seems to control us.

As a practical matter, Haidt suggested, that means taking steps to limit our exposure to technology. His own public-advocacy group, The Anxious Generation Movement, suggests a set of four reforms: No smartphones for kids before they are high-school age; no social media before age 16; making school phone-free, from bell to bell; and giving kids more independence, free play, and responsibility in the world.

Certainly there is movement toward some of these concepts. Some school districts in the U.S. are banning or limiting phone usage; Australia has also instituted a ban on social media for anyone under 16, while a handful of other countries have announced similar plans.

“There’s a gigantic techlash happening right now,” Haidt suggested. For all the sudden changes technology has introduced within the last 15 years, it is still possible, for now, for people to find a way out of our tech-induced predicament.

“The good news is, there is human agency,” Haidt said.

OpenAI is in and Anthropic is out as a supplier of AI technology for the US defense department. This news caps a week of bluster by the highest officials in the US government towards some of the wealthiest titans of the big tech industry, and the overhanging specter of the existential risks posed by a new technology powerful enough that the Pentagon claims it is essential to national security. At issue is Anthropic’s insistence that the US Department of Defense (DoD) could not use its models to facilitate “mass surveillance” or “fully autonomous weapons,” provisions the defense secretary Pete Hegseth ...

OpenAI, the maker of ChaptGPT, is rightfully facing widespread criticism for its decisions to fill the gap the U.S. Department of Defense (DoD) created when rival Anthropic refused to drop its restrictions against using its AI for surveillance and autonomous weapons systems. After protests from both users and employees who did not sign up to support government mass surveillance—early reports show that ChaptGPT uninstalls rose nearly 300% after the company announced the deal—Sam Altman, CEO of OpenAI, conceded that the initial agreement was “opportunistic and sloppy.” He then re-published an internal memo on social media stating that additions to the agreement made clear that “Consistent with applicable laws, including the Fourth Amendment to the United States Constitution, National Security Act of 1947, [and] FISA Act of 1978, the AI system shall not be intentionally used for domestic surveillance of U.S. persons and nationals.”

Trouble is, the U.S. government doesn’t believe “consistent with applicable laws” means “no domestic surveillance.” Instead, for the most part, the government has embraced a lax interpretation of “applicable law” that has blessed mass surveillance and large-scale violations of our civil liberties, and then fought tooth and nail to prevent courts from weighing in. 

"After all, many of the world’s most notorious human rights atrocities have historically been “legal” under existing laws at the time."

“Intentionally” is also doing an awful lot of work in that sentence. For years the government has insisted that the mass surveillance of U.S. persons only happens incidentally (read: not intentionally) because their communications with people both inside the United States and overseas are swept up in surveillance programs supposedly designed to only collect communications outside the United States. 

The company’s amendment to the contract continues in a similar vein, “For the avoidance of doubt, the Department understands this limitation to prohibit deliberate tracking, surveillance, or monitoring of U.S. persons or nationals, including through the procurement or use of commercially acquired personal or identifiable information.” Here, “deliberate” is the red flag given how often intelligence and law enforcement agencies rely on incidental or commercially purchased data to sidestep stronger privacy protections.

Here’s another one: “The AI System shall not be used for unconstrained monitoring of U.S. persons’ private information as consistent with these authorities. The system shall also not be used for domestic law-enforcement activities except as permitted by the Posse Comitatus Act and other applicable law.” What, one wonders, does “unconstrained” mean, precisely—and according to whom? 

Lawyers sometimes call these “weasel words” because they create ambiguity that protects one side or another from real accountability for contract violations. As with the Anthropic negotiations, where the Pentagon reportedly agreed to adhere to Anthropic’s red lines only “as appropriate,” the government is likely attempting to publicly commit to limits in principle, but retain broad flexibility in practice.

OpenAI also notes that the Pentagon promised the NSA would not be allowed to use OpenAI’s tools absent a new agreement, and that its deployment architecture will help it verify that no red lines are crossed. But secret agreements and technical assurances have never been enough to rein in surveillance agencies, and they are no substitute for strong, enforceable legal limits and transparency.

OpenAI executives may indeed be trying, as claimed, to use the company’s contractual relationship with the Pentagon to help ensure that the government should use AI tools only in a way consistent with democratic processes. But based on what we know so far, that hope seems very naïve.

Moreover, that naïvete is dangerous. In a time when governments are willing to embrace extreme and unfounded interpretations of “applicable laws,” companies need to put some actual muscle behind standing by their commitments. After all, many of the world’s most notorious human rights atrocities have historically been “legal” under existing laws at the time. OpenAI promises the public that it will  “avoid enabling uses of AI or AGI that harm humanity or unduly concentrate power,” but we know that enabling mass surveillance does both.     

OpenAI isn’t the only consumer-facing company that is, on the one hand, seeking to reassure the public that they aren’t participating in actions that violate human rights while, on the other, seeking to cash in on government mass surveillance efforts.  Despite this marketing double-speak, it is very clear that companies just cannot do both. It’s also clear that companies shouldn’t be given that much power over the limits of our privacy to begin with. The public should not have to rely on a small group of people—whether CEOs or Pentagon officials—to protect our civil liberties.
