Here is the full transcript of world-renowned AI expert Professor Stuart Russell’s interview on The Diary Of A CEO Podcast with host Steven Bartlett, December 4, 2025.

BRIEF NOTES: Steven Bartlett sits down with legendary AI researcher Professor Stuart Russell, the man who literally wrote the world’s standard textbook on artificial intelligence, for a stark warning about where this technology is heading. Russell explains why leading AI CEOs privately admit there is a non‑trivial risk of human extinction, why they feel trapped in a trillion‑dollar “AGI race,” and why he was told that only a Chernobyl‑scale AI disaster might force governments to act. He breaks down concepts like the “gorilla problem,” fast takeoff, and self‑preserving AI systems, arguing that current architectures are fundamentally unsafe and that we urgently need provably beneficial AI instead. The conversation also explores what work, purpose, and human flourishing could look like in a world where machines can do almost everything better and cheaper than people.

The Man Who Wrote the Textbook on AI

STEVEN BARTLETT: Professor Stuart Russell, OBE. A lot of people have been talking about AI for the last couple of years. It appears you’ve, this really shocked me, it appears you’ve been talking about AI for most of your life.

STUART RUSSELL: Well, I started doing AI in high school back in England, but then I did my PhD starting in ’82 at Stanford. I joined the faculty at Berkeley in ’86. So I’m in my 40th year as a professor at Berkeley. The main thing that the AI community is familiar with in my work is a textbook that I wrote.

STEVEN BARTLETT: Is this the textbook that most students who study AI are likely learning from?

STUART RUSSELL: Yep.

STEVEN BARTLETT: So you wrote the textbook on artificial intelligence 31 years ago. You actually probably started writing it because it’s so bloody big in the year that I was born. So I was born in ’92.

STUART RUSSELL: Yep, took me about two years.

STEVEN BARTLETT: Me and your book are the same age, which just is a wonderful way for me to understand just how long you’ve been talking about this and how long you’ve been writing about this. And actually it’s interesting that many of the CEOs who are building some of the AI companies now probably learned from your textbook.

The Chernobyl Scenario: A Wake-Up Call

You had a conversation with somebody who said that in order for people to get the message that we’re going to be talking about today, there would have to be a catastrophe for people to wake up. Can you give me context on that conversation and a gist of who you had this conversation with?

STUART RUSSELL: So it was with one of the CEOs of a leading AI company. He sees two possibilities, as do I, which is either we have a small or let’s say small scale disaster.

STEVEN BARTLETT: Of the same scale as Chernobyl, the nuclear meltdown in Ukraine.

STUART RUSSELL: Yeah. So this nuclear plant blew up in 1986, killed a fair number of people directly and maybe tens of thousands of people indirectly through radiation. Recent cost estimates more than a trillion dollars. So that would wake people up. That would get the governments to regulate. He’s talked to the governments and they won’t do it.

So he looked at this Chernobyl scale disaster as the best case scenario because then the governments would regulate and require AI systems to be built.

STEVEN BARTLETT: And is this CEO building an AI company?

STUART RUSSELL: He runs one of the leading AI companies.

STEVEN BARTLETT: And even he thinks that the only way that people will wake up is if there’s a Chernobyl level nuclear disaster.

STUART RUSSELL: Yeah, it wouldn’t have to be a nuclear disaster. It would be either an AI system that’s being misused by someone, for example, to engineer a pandemic, or an AI system that does something itself, such as crashing our financial system or our communication systems. The alternative is a much worse disaster where we just lose control altogether.

Private Conversations: The Paradox of the AI Race

STEVEN BARTLETT: You have had lots of conversations with lots of people in the world of AI, both people that have built the technology, have studied and researched the technology, or the CEOs and founders that are currently in the AI race. What are some of the interesting sentiments that the general public wouldn’t believe that you hear privately about their perspectives?

Because I find that so fascinating. I’ve had some private conversations with people very close to these tech companies, and the shocking sentiment that I was exposed to was that they are aware of the risks often, but they don’t feel like there’s anything that can be done. So they’re carrying on, which feels like a bit of a paradox to me.

STUART RUSSELL: Yes. It must be a very difficult position to be in, in a sense. Right. You’re doing something that, you know, has a good chance of bringing an end to life on Earth, including that of yourself and your own family. They feel that they can’t escape this race.

If a CEO of one of those companies was to say, “We’re not going to do this anymore,” they would just be replaced. Because the investors are putting their money up because they want to create AGI and reap the benefits of it.

It’s a strange situation where at least all the ones I’ve spoken to, I haven’t spoken to Sam Altman about this, but, you know, Sam Altman, even before becoming CEO of OpenAI, said that creating superhuman intelligence is the biggest risk to human existence that there is.

STEVEN BARTLETT: “My worst fears are that we, the field, the technology, the industry, cause significant harm to the world.”

STUART RUSSELL: You know, Elon Musk is also on record saying this.
