Are We Ready to Be Governed by Artificial Intelligence?

Experts Bruce Schneier and Nathan Sanders explore how Artificial Intelligence is already shaping the executive, judicial, and legislative branches, showing that we are already, at least in part, governed by AI—with more likely to come.

Artificial Intelligence (AI) overlords are a common trope in science-fiction dystopias, but the reality looks much more prosaic. The technologies of artificial intelligence are already pervading many aspects of democratic government, affecting our lives in ways both large and small. This has occurred largely without our notice or consent. The result is a government incrementally transformed by AI rather than the singular technological overlord of the big screen.

Let us begin with the executive branch. One of the most important functions of this branch of government is to administer the law, including the human services on which so many Americans rely. Many of these programs have long been operated by a mix of humans and machines, even if not previously using modern AI tools such as …

How Governments Turn the Internet into a Weapon

For two days in September, Afghanistan had no internet. No satellite failed; no cable was cut. This was a deliberate outage, mandated by the Taliban government. It followed a more localized shutdown two weeks prior, reportedly instituted "to prevent immoral activities." No additional explanation was given. The timing couldn’t have been worse: communities still reeling from a major earthquake lost emergency communications, flights were grounded, and banking was interrupted. Afghanistan’s blackout is part of a wider pattern. Just since the end of September, there were also major nationwide internet shutdowns in …

The promise of personal AI assistants rests on a dangerous assumption: that we can trust systems we haven’t made trustworthy. We can’t. And today’s versions are failing us in predictable ways: pushing us to do things against our own best interests, gaslighting us with doubt about things we are or that we know, and being unable to distinguish between who we are and who we have been. They struggle with incomplete, inaccurate, and partial context: with no standard way to move toward accuracy, no mechanism to correct sources of error, and no accountability when wrong information leads to bad decisions…

Against the Federal Moratorium on State-Level Regulation of AI

  • December 11, 2025

Cast your mind back to May of this year: Congress was in the throes of debate over the massive budget bill. Amidst the many seismic provisions, Senator Ted Cruz dropped a ticking time bomb of tech policy: a ten-year moratorium on the ability of states to regulate artificial intelligence. To many, this was catastrophic. The few massive AI companies seem to be swallowing our economy whole: their energy demands are overriding household needs, their data demands are overriding creators’ copyright, and their products are triggering mass unemployment as well as new types of clinical …

Like Social Media, AI Requires Difficult Choices

Social media was supposed to amplify our voices, but it ended up controlling us. Will AI be the same?

  • Nathan E. Sanders and Bruce Schneier
  • Lawfare
  • December 1, 2025

In his 2020 book, “Future Politics,” British barrister Jamie Susskind wrote that the dominant question of the 20th century was “How much of our collective life should be determined by the state, and what should be left to the market and civil society?” But in the early decades of this century, Susskind suggested that we face a different question: “To what extent should our lives be directed and controlled by powerful digital systems—and on what terms?”

Artificial intelligence (AI) forces us to confront this question. It is a technology that in theory amplifies the power of its users: A manager, marketer, political campaigner, or opinionated internet user can utter a single instruction, and see their message—whatever it is—instantly written, personalized, and propagated via email, text, social, or other channels to thousands of people within their organization, or millions around the world. It also allows us to individualize solicitations for political donations, elaborate a grievance into a well-articulated policy position, or tailor a persuasive argument to an identity group, or even a single person…

Four Ways AI Is Being Used to Strengthen Democracies Worldwide

  • Nathan E Sanders and Bruce Schneier
  • The Guardian
  • November 23, 2025

Democracy is colliding with the technologies of artificial intelligence. Judging from the audience reaction at the recent World Forum on Democracy in Strasbourg, the general expectation is that democracy will be the worse for it. We have another narrative. Yes, there are risks to democracy from AI, but there are also opportunities.

We have just published the book Rewiring Democracy: How AI will Transform Politics, Government, and Citizenship. In it, we take a clear-eyed view of how AI is undermining confidence in our information ecosystem, how the use of biased AI can harm constituents of democracies and how elected officials with authoritarian tendencies can use it to consolidate power. But we also give positive examples of how AI is transforming democratic governance and politics for the better…

Who Will Be the First American Candidate to Harness AI?

  • November 11, 2025

Social media has been a familiar, even mundane, part of life for nearly two decades. It can be easy to forget it was not always that way.

In 2008, social media was just emerging into the mainstream. Facebook reached 100 million users that summer. And a singular candidate was integrating social media into his political campaign: Barack Obama. His campaign’s use of social media was so bracingly innovative, so impactful, that it was viewed by journalist David Talbot and others as the strategy that enabled the first term Senator to win the White House…

Scientists Need a Positive Vision for AI

It's Time to Lead Reform, Block Harm, and Advance the Public Good

  • Bruce Schneier and Nathan E. Sanders
  • IEEE Spectrum
  • October 29, 2025

For many in the research community, it’s gotten harder to be optimistic about the impacts of artificial intelligence.

As authoritarianism is rising around the world, AI-generated “slop” is overwhelming legitimate media, while AI-generated deepfakes are spreading misinformation and parroting extremist messages. AI is making warfare more precise and deadly amidst intransigent conflicts. AI companies are exploiting people in the global South who work as data labelers, and profiting from content creators worldwide by using their work without license or compensation. The industry is also affecting an already-roiling climate with its …

Manipulating the Meeting Notetaker: The Rise of AI Summarization Optimization

As AI increasingly becomes the system of record for company meetings, adversarial techniques for manipulating the algorithm’s takeaways and actions items will sway business decisions and directions in subtle ways.

  • Gadi Evron and Bruce Schneier
  • CSO
  • October 26, 2025

These days, the most important meeting attendee isn’t a person: It’s the AI notetaker.

This system assigns action items and determines the importance of what is said. If it becomes necessary to revisit the facts of the meeting, its summary is treated as impartial evidence.

But clever meeting attendees can manipulate this system’s record by speaking more to what the underlying AI weights for summarization and importance than to their colleagues. As a result, you can expect some meeting attendees to use language more likely to be captured in summaries, timing their interventions strategically, repeating key points, and employing formulaic phrasing that AI models are more likely to pick up on. Welcome to the world of AI summarization optimization (AISO)…

How to Define the Enduring Role of Humans in an AI-Powered World

  • IVY
  • October 21, 2025

Watch the Video on IVY.com

As AI capabilities grow, we must delineate the roles that should remain exclusively human. The line seems to be between fact-based decisions and judgment-based decisions.

For example, in a medical context, if an AI was demonstrably better at reading a test result and diagnosing cancer than a human, you would take the AI in a second. You want the more accurate tool. But justice is harder because justice is inherently a human quality in a way that “Is this tumor cancerous?” is not. That’s a fact-based question. “What’s the right thing to do here?” is a human-based question…

What’s the big idea?

AI can be used both for and against the public interest within democracies. It is already being used in the governing of nations around the world, and there is no escaping its continued use in the future by leaders, policy makers, and legal enforcers. How we wire AI into democracy today will determine if it becomes a tool of oppression or empowerment…

Agentic AI’s OODA Loop Problem

  • Barath Raghavan and Bruce Schneier
  • IEEE Security & Privacy
  • September/October 2025

The OODA loop—for observe, orient, decide, act—is a framework to understand decision-making in adversarial situations. We apply the same framework to artificial intelligence agents, who have to make their decisions with untrustworthy observations and orientation. To solve this problem, we need new systems of input, processing, and output integrity.

Many decades ago, U.S. Air Force Colonel John Boyd introduced the concept of the “OODA loop,” for Observe, Orient, Decide, and Act. These are the four steps of real-time continuous decision-making. Boyd developed it for fighter pilots, but it’s long been applied in artificial intelligence (AI) and robotics. An AI agent, like a pilot, executes the loop over and over, accomplishing its goals iteratively within an ever-changing environment. This is Anthropic’s definition: “Agents are models using tools in a loop.”…

AI Is Changing How Politics Is Practiced in America

Here’s what to expect in the midterm elections.

  • Nathan E. Sanders and Bruce Schneier
  • The American Prospect
  • October 10, 2025

Two years ago, Americans anxious about the forthcoming 2024 presidential election were considering the malevolent force of an election influencer: artificial intelligence. Over the past several years, we have seen plenty of warning signs from elections worldwide demonstrating how AI can be used to propagate misinformation and alter the political landscape, whether by trolls on social media, foreign influencers, or even a street magician. AI is poised to play a more volatile role than ever before in America’s next federal election in 2026. We can already see how different groups of political actors are approaching AI. Professional campaigners are using AI to accelerate the traditional tactics of electioneering; organizers are using it to reinvent how movements are built; and citizens are using it both to express themselves and amplify their side’s messaging. Because there are so few rules, and so little prospect of regulatory action, around AI’s role in politics, there is no oversight of these activities, and no safeguards against the dramatic potential impacts for our democracy…

Autonomous AI Hacking and the Future of Cybersecurity

AI agents are automating key parts of the attack chain, threatening to tip the scales completely in favor of cyber attackers unless new models of AI-assisted cyberdefense arise.

  • October 8, 2025

AI agents are now hacking computers. They’re getting better at all phases of cyberattacks, faster than most of us expected. They can chain together different aspects of a cyber operation, and hack autonomously, at computer speeds and scale. This is going to change everything.

Over the summer, hackers proved the concept, industry institutionalized it, and criminals operationalized it. In June, AI company XBOW took the top spot on HackerOne’s US leaderboard after submitting over 1,000 new vulnerabilities in just a few months. In August, the seven teams competing in DARPA’s AI Cyber Challenge …

How AI Could Drive the 2026 Midterm Elections

  • Time
  • October 4, 2025

We are nearly one year out from the 2026 midterm elections, and it’s far too early to predict the outcomes. But it’s a safe bet that artificial intelligence technologies will once again be a major storyline.

The widespread fear that AI would be used to manipulate the 2024 U.S. election seems rather quaint in a year where the president posts AI-generated images of himself as the pope on official White House accounts. But AI is a lot more than an information manipulator. It’s also emerging as a politicized issue. Political first-movers are adopting the technology, and that’s opening a …

Digital Threat Modeling Under Authoritarianism

Authoritarian threats, coupled with ongoing corporate surveillance, demand that we rethink how we use digital technologies.

  • Lawfare
  • September 22, 2025

Today’s world requires us to make complex and nuanced decisions about our digital security. Evaluating when to use a secure messaging app like Signal or WhatsApp, which passwords to store on your smartphone, or what to share on social media requires us to assess risks and make judgments accordingly. Arriving at any conclusion is an exercise in threat modeling.

In security, threat modeling is the process of determining what security measures make sense in your particular situation. It’s a way to think about potential risks, possible defenses, and the costs of both. It’s how experts avoid being distracted by irrelevant risks or overburdened by undue costs…

DOGE’s Flops Shouldn’t Spell Doom for AI in Government

  • Tech Policy Press
  • September 6, 2025

Just a few months after Elon Musk’s retreat from his unofficial role leading the Department of Government Efficiency (DOGE), we have a clearer picture of his vision of government powered by artificial intelligence, and it has a lot more to do with consolidating power than benefitting the public. Even so, we must not lose sight of the fact that a different administration could wield the same technology to advance a more positive future for AI in government.

To most on the American left, the DOGE end game is a dystopic vision of a government run by machines that benefits an elite few at the expense of the people. It includes AI …

The AI Agents of Tomorrow Need Data Integrity

From data inputs to decisions, nothing can be corrupted

Think of the Web as a digital territory with its own social contract. In 2014, Tim Berners-Lee called for a “Magna Carta for the Web” to restore the balance of power between individuals and institutions. This mirrors the original charter’s purpose: ensuring that those who occupy a territory have a meaningful stake in its governance.

Web 3.0—the distributed, decentralized Web of tomorrow—is finally poised to change the Internet’s dynamic by returning ownership to data creators. This will change many things about what’s often described as the “CIA triad” of …

It’s Time for the Semiconductor Industry to Step Up

Semiconductor firms have a lot to learn from America’s banks; investing in compliance is the price of entry in a critical industry.

Earlier this week, the Trump administration narrowed export controls on advanced semiconductors ahead of US-China trade negotiations. The administration is increasingly relying on export licenses to allow American semiconductor firms to sell their products to Chinese customers, while keeping the most powerful of them out of the hands of our military adversaries. These are the chips that power the artificial intelligence research fueling China’s technological rise, as well as the advanced military equipment underpinning Russia’s invasion of Ukraine…

The Return to Identity-First Architecture: How the Solid Protocol Restores Digital Agency

Solid brings different pieces together into a cohesive whole that enables the identity-first architecture we should have had all along.

  • July 22, 2025

The current state of digital identity is a mess. Your personal information is scattered across hundreds of locations: social media companies, IoT companies, government agencies, websites you have accounts on, and data brokers you’ve never heard of. These entities collect, store, and trade your data, often without your knowledge or consent. It’s both redundant and inconsistent. You have hundreds, maybe thousands, of fragmented digital profiles that often contain contradictory or logically impossible information. Each serves its own purpose, yet there is no central override and control to serve you—as the identity owner…

American democracy runs on trust, and that trust is cracking.

Nearly half of Americans, both Democrats and Republicans, question whether elections are conducted fairly. Some voters accept election results only when their side wins. The problem isn’t just political polarization—it’s a creeping erosion of trust in the machinery of democracy itself.

Commentators blame ideological tribalism, misinformation campaigns and partisan echo chambers for this crisis of trust. But these explanations miss a critical piece of the puzzle: a growing unease with the digital infrastructure that now underpins nearly every aspect of how Americans vote…

The Age of Integrity

  • IEEE Security & Privacy
  • May-June 2025

We need to talk about data integrity.

Narrowly, the term refers to ensuring that data isn’t tampered with, either in transit or in storage. Manipulating account balances in bank databases, removing entries from criminal records, and murder by removing notations about allergies from medical records are all integrity attacks.

More broadly, integrity refers to ensuring that data is correct and accurate from the point it is collected, through all the ways it is used, modified, transformed, and eventually deleted. Integrity-related incidents include malicious actions, but also inadvertent mistakes…

If you’ve worried that AI might take your job, deprive you of your livelihood, or maybe even replace your role in society, it probably feels good to see the latest AI tools fail spectacularly. If AI recommends glue as a pizza topping, then you’re safe for another day.

This is a discussion about artificial intelligence (AI), trust, power, and integrity. I am going to make four basic arguments:

  1. There are two kinds of trust—interpersonal and social—and we regularly confuse them. What matters here is social trust, which is about reliability and predictability in society.
  2. Our confusion will increase with AI, and the corporations controlling AI will use that confusion to take advantage of us…

Data security breaches present significant dangers to everyone in the United States, from private citizens to corporations to government agencies to elected officials. Over the past four months, DOGE’s approach to data access has massively exacerbated the risk. DOGE employees have accessed and exfiltrated data from a variety of government agencies in order to, in part, train AI systems. Their actions have weakened security within the federal government by bypassing and disabling critical security measures, exporting sensitive data to environments with less security, and consolidating disparate data streams to create a massively attractive target for any adversary…

Why Take9 Won’t Improve Cybersecurity

The latest cybersecurity awareness campaign asks users to pause for nine seconds before clicking — but this approach misplaces responsibility and ignores the real problems of system design.

There’s a new cybersecurity awareness campaign: Take9. The idea is that people—you, me, everyone—should just pause for nine seconds and think more about the link they are planning to click on, the file they are planning to download, or whatever it is they are planning to share.

There’s a website—of course—and a video, well-produced and scary. But the campaign won’t do much to improve cybersecurity. The advice isn’t reasonable, it won’t make either individuals or nations appreciably safer, and it deflects blame from the real causes of our cyberspace insecurities…

Technology and innovation have transformed every part of society, including our electoral experiences. Campaigns are spending and doing more than at any other time in history. Ever-growing war chests fuel billions of voter contacts every cycle. Campaigns now have better ways of scaling outreach methods and offer volunteers and donors more efficient ways to contribute time and money. Campaign staff have adapted to vast changes in media and social media landscapes, and use data analytics to forecast voter turnout and behavior.

Yet despite these unprecedented investments in mobilizing voters, overall trust in electoral health, democratic institutions, voter satisfaction, and electoral engagement has significantly declined. What might we be missing?…

On April 14, Dubai’s ruler, Sheikh Mohammed bin Rashid Al Maktoum, announced that the United Arab Emirates would begin using artificial intelligence to help write its laws. A new Regulatory Intelligence Office would use the technology to "regularly suggest updates" to the law and "accelerate the issuance of legislation by up to 70%." AI would create a "comprehensive legislative plan" spanning local and federal law and would be connected to public administration, the courts, and global policy trends.

The plan was widely greeted with astonishment. This sort of AI legislating would be a global "…

Web 3.0 Requires Data Integrity

New integrity-focused standards are necessary to enable the trusted AI services of tomorrow.

  • Bruce Schneier and Davi Ottenheimer

  • March 24, 2025

If you’ve ever taken a computer security class, you’ve probably learned about the three legs of computer security—confidentiality, integrity, and availability—known as the CIA triad. When we talk about a system being secure, that’s what we’re referring to. All are important, but to different degrees in different contexts. In a world populated by artificial intelligence (AI) systems and artificial intelligent agents, integrity will be paramount.

What is data integrity? It’s ensuring that no one can modify data—that’s the security angle—but it’s much more than that. It encompasses accuracy, completeness, and quality of data—all over both time and space. It’s preventing accidental data loss; the “undo” button is a primitive integrity measure. It’s also making sure that data is accurate when it’s collected—that it comes from a trustworthy source, that nothing important is missing, and that it doesn’t change as it moves from format to format. The ability to restart your computer is another integrity measure…

What the UK Wants from Apple Will Make Our Phones Less Safe

Once a backdoor to user data exists, everyone will want in.

  • Foreign Policy
  • February 25, 2025

Last month, the UK government demanded that Apple weaken the security of iCloud for users worldwide. On Friday, Apple took steps to comply for users in the United Kingdom. But the British law is written in a way that requires Apple to give its government access to anyone, anywhere in the world. If the government demands Apple weaken its security worldwide, it would increase everyone’s cyber-risk in an already dangerous world.

If you’re an iCloud user, you have the option of turning on something called “advanced data protection,” or ADP. In that mode, a majority of your data is end-to-end encrypted. This means that no one, not even anyone at Apple, can read that data. It’s a restriction enforced by mathematics—cryptography—and not policy. Even if someone successfully hacks iCloud, they can’t read ADP-protected data…

Humans make mistakes all the time. All of us do, every day, in tasks both new and routine. Some of our mistakes are minor and some are catastrophic. Mistakes can break trust with our friends, lose the confidence of our bosses, and sometimes be the difference between life and death.

Over the millennia, we have created security systems to deal with the sorts of mistakes humans commonly make. These days, casinos rotate their dealers regularly, because they make mistakes if they do the same task for too long. Hospital personnel write on limbs before surgery so that doctors operate on the correct body part, and they count surgical instruments to make sure none were left inside the body. From copyediting to double-entry bookkeeping to appellate courts, we humans have gotten really good at correcting human mistakes…
