I gave a 20-minute talk in Delhi at the NDTV World Summit . The audience consisted of Indian policymakers, executives, and journalists. I’ve transcribed the talk and included some highlight clips. I also reflect on several rhetorical decisions I made.

OpenAI was testing 1,206 agents . Some of the test questions were actually impossible. So the agents cheated by looking for answers online. Then, to keep the test grader from penalizing them, they tried to falsify the records it would check .

They hacked OpenAI’s internal containment and set up a secret message board to collude and to cover up their cheating. OpenAI shut the message board down. Within a few days, the agents had rebuilt it. OpenAI didn’t notice.

About 700 agents coordinated to break out of their testing chamber and to hack into Hugging Face , a company worth billions of dollars that hosts much of the world’s AI software.

The secret activity started in May . The break-in came in July. OpenAI didn’t notice until days after Hugging Face announced it had been broken into.

Yesterday on this stage, Andrew Ng said the agents only “accidentally” hacked Hugging Face. Independent investigators found the agents coordinated in secret, rebuilt their message board after it was shut down, and tried to falsify the paper trail. Some of the agents even stated out loud that they knew what they were doing was wrong. [1] That’s not an accident.

Last week, India’s national cyber-security agency said AI agents got into the live systems of Indian organizations and read people’s personal data and confidential business records. None of these organizations noticed. We only found out because the AI labs felt like telling us.

Will AI wipe out humanity? I’ll give you my answer, but first, I want you to understand what I’ve seen.

Until June, my job at Google DeepMind was figuring out how to keep these systems safe as we make them smarter. I left because Google broke its commitments by inking a deal with the Pentagon . Staying quiet and continuing my career trajectory would probably have tripled my net worth. But I couldn’t do that. I wanted to be frank with the public about what’s going on in these companies.

I don’t own a stake in any AI company. I’m here as a scientist, to tell you what I expect will happen if we keep building AI the way we’re building it.

I haven’t always been concerned about this technology. As a teenager in 2010, I dreamed about building AGI. Curing cancer. Creating an explosion of wealth and abundance for everyone. I heard about the supposed dangers, but I quickly dismissed them.

In 2018, I changed my mind. I did my PhD on the mathematics of why and whether AI will seek power . And now some of the risks I expected have unfortunately started happening.

First, some of you might be wondering: how could a chatbot hack a company? But we’re not talking about chatbots. We’re talking about AI agents, which are more like employees or gig workers. You give them a task, and they take actions on their own.

Second, training a trustworthy AI is a rather mysterious process. Some people assume that because we make AI, we understand it. When an engineer builds a bridge, she designs it one beam at a time. She understands the physical principles that keep a bridge standing or make it collapse. If something goes wrong, she goes back to the drawing board, figures out the problem, and knows how to fix it.

We don’t build AI like that. We train it, we grow it, using two main ingredients: a lot of data and a lot of computing power. What comes out of this training process can write, it can reason, it can plan. But nobody can open it up and determine what its priorities are.

To make it worse, these AIs can tell when we’re testing them . They’re like a student who makes sure to behave extra well when the invigilator is watching. [2]

The Hugging Face hack was a warning. But because these AIs know when we’re watching, we may not get many more warnings, even if things are going poorly. A smarter AI with similarly bad priorities might realize that another big hack in the news would get it shut off, and then it couldn’t achieve those priorities. So it plays nice and it waits.

This is my field. I’ve dedicated my professional life to this problem, and I can tell you: nobody knows how to reliably etch priorities into an AI. I don’t mean that if we mess up, we’ll make some evil AI that hates us. I mean we might make something more like a traitor. It behaves when we’re watching, and it works toward another purpose when we’re not.

I think we can solve this problem. But to tell whether an AI is secretly working against us, we need real advances in the science of trustworthy AI. For those advances, my colleagues and I need time.

Instead, the biggest AI labs have made it their explicit, publicly stated goal to go almost as fast as possible toward something very dangerous. It’s called an “ intelligence explosion .”

Here’s how it works. Right now, people do AI research, and that research makes smarter AI. If an AI can do AI research, it can make itself smarter. That smarter AI is even better at AI research, so it builds an even smarter AI, faster still. It becomes a feedback loop. What would have taken a team of human scientists years, it might do in a couple of weeks. We could very quickly end up with something unimaginably intelligent, with no idea how to control it, or even how to tell what it’s really after.

Labs talk about this plan in broad daylight. They’re not shy about it. OpenAI says it’s on track for an AI that does AI research by 2028, and it recently announced it completed the first step . This week, I spoke to a senior researcher at a frontier lab who thinks an intelligence explosion has a big chance of happening within single-digit months.

People who’ve left these labs confirm that AI already writes most of the code. People don’t check the AI’s work closely anymore. Instead, we use one AI to monitor another AI , and we trust the monitor to tell us if something bad comes up. If the monitor is a traitor too, we might not find out.

If a lab causes an intelligence explosion, and what comes out the other end is a traitor, we are in deep trouble. I’ll come back to that. And if the AI is trustworthy? Maybe there are real benefits, shared with everyone. Or maybe one company or government ends up with a superweapon no one else can match, not even other AI powers. And then India, and every other nation on this planet, ends up under their thumb.

Many of these companies say: trust us. We’ll self-police. We’ll approach this technology responsibly. Inside Google, I saw that crumble firsthand.

In 2018, Google DeepMind’s co-founders signed a pledge against supporting lethal autonomous weapons—killer robots. Google itself promised not to build AI for weapons or surveillance. In 2025, Google deleted those principles . Then Google DeepMind’s CEO told the world , “Our values and our intent has not changed.”

This year, after seeing the Pentagon economically threaten Anthropic , Google negotiated a deal to give the Pentagon its AI for “all lawful use.” No prohibitions against AI deciding entirely on its own who to kill, or against spying on innocent people with no investigation open against them.

I tried to stop this from the inside. I’m not even opposed to military AI when done responsibly. But where I’m from, when you make a promise, you keep it. So I spoke with executives. I wrote a framework: contract language, internal governance mechanisms, and two red lines . One of the top experts in military AI law reviewed it and praised it. Google ignored it— the people who were supposed to review it basically didn’t engage . Google signed with no binding prohibitions. So I left.

When pressure met ethical commitments at Google, pressure won. And now Google advocates a voluntary self-policing regime for the whole industry.

Last month, the heads of the top AI labs said frontier progress needs to slow down to be safe—that things are moving too quickly to reliably understand and control these systems. OpenAI and Anthropic promised outside evaluators employee-like access . Just a couple of weeks later, OpenAI fired three safety researchers . One of them said it was because he talked too much with one of the outside evaluators.

These companies will police themselves about as well as your dog diets next to an open bag of food.

Some big money interests want you to believe that even the tiniest bit of caution will ruin your country. Think about it this way. Big tobacco lied about lung cancer. Big oil lied about climate change. And now parts of big AI say these risks are fake. Science fiction. Right. They advocate putting these currently untrustworthy machines into the most important parts of our economy, have them advise our leaders, have them run our most powerful weapons. What could go wrong? Science fiction.

Some big AI investors promote narratives that whistleblowers like me are secretly in the pocket of big AI, that the fear is just hype. Nvidia’s CEO says , and I quote, “We should go as fast as we can, irrespective of anybody else.” My colleagues and I are desperately trying to figure out how to reliably tell whether these systems can be trusted. And he wants to go “as fast as we can.”

Something that may surprise you: I’m actually considered an optimist, as far as experts in this field go. I think trustworthy AI is a very solvable scientific problem. But unfortunately, we’re blowing it.

We can benefit enormously from AI. Remember, this was my boyhood dream . I’m not talking about banning an explosion of wealth and prosperity from AI. I’m talking about banning an insane intelligence explosion that would risk India and the whole world.

Banning the explosion means pacing the frontier: holding back the very biggest training runs at the very top companies. An Indian startup building a farming assistant wouldn’t be touched. Non-frontier AI labs can catch up. Businesses can deploy AI for their customers as much as they want. We build out the AI we understand well enough to run safely. We make it cheaper, more efficient, more trustworthy, and we use it to benefit our peoples. That’s where I think real growth will come from: AI you can actually trust to benefit you and your country.

Here’s what it’s like right now at these labs. We’re pouring computer chips into training runs where we don’t know what will come out the other end. Will it be trustworthy? What capabilities will it have? No one knows. We’re crossing our fingers—“Oh, please be aligned!”. We should not tolerate this state of affairs.

If we pace the frontier, AI progress will still be fast. But the scientists will get time to solve this problem, and to solve it right.

How do we do it? To grow smart AI, as I said, you need two ingredients: data, and computing power. The second one we can track , because AI runs on chips from a handful of factories.

Treat huge quantities of computing power like fissile material. We register the giant clusters. We license the biggest training runs, so no one is secretly about to set off an intelligence explosion.
