A.I., Mars and Immortality: Are We Dreaming Big Enough? – Peter Thiel (Transcript)

Read the full transcript of billionaire Peter Thiel’s interview on Interesting Times with Ross Douthat podcast titled “A.I., Mars and Immortality: Are We Dreaming Big Enough?”, June 26, 2025.

The Case for Technological Stagnation

ROSS DOUTHAT: Is Silicon Valley recklessly ambitious? What should we fear more, Armageddon or stagnation? Why is one of the world’s most successful investors worrying about the Antichrist?

My guest today is the co-founder of PayPal and Palantir and an early investor in the political careers of Donald Trump and J.D. Vance. Peter Thiel is the original tech right power player, well known for funding a range of conservative and simply contrarian ideas. But we’re going to talk about his own ideas because despite the slight handicap of being a billionaire, there’s a good case that he’s the most influential right wing intellectual of the last 20 years. Peter Thiel, welcome to Interesting Times.

PETER THIEL: Thanks for having me.

ROSS DOUTHAT: You’re very welcome. Thanks for being here. So I want to start by taking you back in time about 13 or 14 years. You wrote an essay for National Review, the conservative magazine called “The End of the Future.” And basically the argument in that essay was that the dynamic, fast-paced, ever-changing modern world was just not nearly as dynamic as people thought.

And that actually we entered a period of technological stagnation. That sort of digital life was a breakthrough, but not as big a breakthrough as people had hoped. And that sort of the world was kind of stuck, basically. And you weren’t the only person to make arguments like this, but it had a special potency coming from you because you were a Silicon Valley insider who had gotten rich in the digital revolution. So I’m curious, in 2025, right, do you think that diagnosis still holds?

PETER THIEL: Yes, I still broadly believe in the stagnation thesis. It was never an absolute thesis. So the claim was not that we were absolutely completely stuck. It was in some ways a claim about that the velocity had slowed, it wasn’t zero, but that we were, I don’t know, from 1750 to 1970.

Two hundred plus years were periods of accelerating change where we’re relentlessly, we’re moving faster. The ships were faster, the railroads were faster, the cars were faster, the planes were faster. It culminates in the Concorde and the Apollo missions and then that in all sorts of dimensions things had slowed.

There was, you know, I always made an exception for the world of bits. So we had, you know, computers and software and Internet and mobile Internet. And then, you know, the last 10, 15 years you had crypto and the AI revolution, which I think is, is, is in some sense pretty big. But, but the question is, you know, is it enough to, to really get out of this, this generalized sense of stagnation?

And there’s an epistemological question you can start with on the, you know, the, the “Back to the Future” essays. How do we even, how do we even know whether we’re in stagnation or acceleration? Because one of the features of late modernity is that people are hyper specialized. And so, you know, you know, can you say that we’re not making progress in physics unless you’ve devoted half your life to studying string theory? Or what about quantum computers or what about cancer research and biotech and sort of all these verticals and then how much does progress in cancer count versus string theory?

And so you have to give weightings to all these things. So in theory, it’s an extremely, extremely difficult question to get a handle of because, yeah, the fact that it’s so hard to answer that we have ever narrower groups of guardians guarding themselves is itself cause for skepticism. And so, yes, I think broadly we’re in this world that’s still pretty stuck. It’s not absolutely stuck.

The Back to the Future Test

ROSS DOUTHAT: Yeah, you mentioned “Back to the Future” and we just showed our kids the original “Back to the Future,” the first one with Michael J. Fox, and of course it was like.

PETER THIEL: 1955 to 1985, 30 years back. And then the “Back to the Future Two” was I think 1985 to 2015, which is now a decade in the past. And that’s where you had flying cars. And the 2015 future is wildly divergent.

ROSS DOUTHAT: From the United States. The 2015 future did have Biff Tannen as a Donald Trump-like figure in some kind of power. So it had some kind of prescience. But yeah, the big noticeable thing is just how different the built environment looks.

And so one of the strongest cases for stagnation that I’ve heard is that, yeah, if you put someone in a time machine from various points, they would recognize themselves to be in a completely different world if they left 1860 or.

PETER THIEL: 1890 to 1970, if you lived, those are the 80 years of your lifetime, something like that.

ROSS DOUTHAT: But the world just to my kids, even, you know, as children of 2025, looking at 1985, it’s like the cars are a little different and no one has phones, but the world seems fairly similar. So that’s a kind of, that’s a kind of non-statistical. But that’s the common sense. It’s a common sense understanding.

But are there like, what, what would convince you that we were living through a period of takeoff? Is it just economic growth? Is it productivity growth? Like what are, are there numbers for stagnation versus dynamism that you look at?

PETER THIEL: Sure, it would be well, the economic number would just be how, you know, what are your living standards compared to your parents? You know, if you’re a 30-year-old millennial or you know, how are you doing versus when your parent, your boomer parents were 30 years old, how did they do at the time?

There are intellectual questions, how much, you know, how many breakthroughs are we having?
