Transcript: Walter Isaacson Interviews Elon Musk – The Builders Podcast  

In this debut episode of The Builders podcast, Walter Isaacson interviews Elon Musk about the future of artificial intelligence, why he believes AI should be maximally truth-seeking and curious, and how robots and space could grow the economy a million times over. Musk also reflects on his year in politics with DOGE, simulation theory, wealth and taxes, empathy and immigration, and whether humans will stay in control in a world of superintelligence. Read the full transcript of this conversation below:

Introduction

WALTER ISAACSON: (00:00:38 – 00:01:34) I’m Walter Isaacson, and this is The Builders. It’s a series of conversations with the most consequential minds shaping our future. And I want to start with Elon Musk. Elon has lived a lot of lives since I last wrote about him. He went into government with DOGE. He became a trillionaire with the SpaceX IPO, he bought Cursor AI, a company that turns individual coders into entire engineering teams. And he’s shifting his solar energy strategy from panels on Earth to harnessing it from systems in space.

He’s a relentless builder with incredible power, and his inventions and companies are destined to reverberate across humanity. So let’s ask him about the future he believes that he’s building. Elon Musk.

ELON MUSK: (00:01:34 – 00:01:34) Hey, Walter.

WALTER ISAACSON: (00:01:35 – 00:01:36) Welcome to The Builders.

ELON MUSK: (00:01:37 – 00:01:37) Thanks.

Participant or Spectator in AI

WALTER ISAACSON: (00:01:38 – 00:01:55) I’ve watched you, I think, be maybe mercurial or waver in how sanguine you are about artificial intelligence. Sometimes you feel it’s an existential threat, right? Now you seem to be going with the flow. Tell me how you’re feeling about it.

ELON MUSK: (00:01:55 – 00:02:20) Well, I do think it’s at least some percentage chance of it being an existential threat. So, but there’s nothing I can do to stop it. So I felt— I basically came to the conclusion I’ve got 2 choices, which is either be a participant or a spectator. And I guess being a participant is more interesting than being a spectator. And maybe I can shape it, hopefully in a good direction. Maybe.

Truth-Seeking and Curious AI as a Foundation for Safety

WALTER ISAACSON: (00:02:20 – 00:02:23) And if you were to shape it, how? Make it maximally truth-seeking?

ELON MUSK: (00:02:24 – 00:02:27) Yeah, I think that’s certainly an important foundation.

WALTER ISAACSON: (00:02:27 – 00:02:28) And make it curious?

ELON MUSK: (00:02:29 – 00:03:30) Yeah, curious, truth-seeking. I think these are important elements of safety. Whereas if you try to force an AI to believe 2 things that cannot mutually be true, they can’t both be true, but you tell AI, “A is true and B is true,” even though A and B contradict each other. And if that happens at a foundational level, you can make the AI insane.

In fact, I think that was at least part of the lesson that Arthur C. Clarke was trying to convey in 2001: A Space Odyssey. The ship AI was told to take the astronauts to the monolith, but also that they could not know about the monolith. It was secret. And so it came to the conclusion that it must take them there dead. And thus, so it basically forced the, I think part of what Arthur C. Clarke was trying to say is, “Don’t force an AI to lie.”

WALTER ISAACSON: (00:03:31 – 00:03:39) And if you make it maximally truth-seeking and curious, like you say, I don’t quite get it. Why does that make it safer?

ELON MUSK: (00:03:40 – 00:04:19) Well, if you force an AI to believe 2 mutually inconsistent things, you can make it go insane. And an insane AI, I think, is not a safe one. Then curious, I think, is important because a curious AI, I think, is going to want to foster humanity to see how we turn out. So what happens to a humanity that prospers and becomes multi-planetary. I think a curious AI will want to foster humanity. A future where there are humans on multiple planets is more interesting than one where there are not any humans on the planets.

Simulation Theory and Not Being Boring

WALTER ISAACSON: (00:04:19 – 00:04:22) So the most interesting outcome is the most likely?

ELON MUSK: (00:04:22 – 00:04:31) Yes. Well, generally, I think that’s true for a different reason, which is that if simulation theory is correct, then any simulations that are boring will be truncated.

WALTER ISAACSON: (00:04:33 – 00:04:34) And is simulation theory correct?

ELON MUSK: (00:04:34 – 00:04:41) The fact that we exist means that we are an interesting simulation. And really the most important thing is just don’t be boring.

WALTER ISAACSON: (00:04:42 – 00:04:53) This explains you a bit. You’re on a crusade against being boring. Well, I’ve heard you talk about this a bit. I really do need to know, how convinced are you that we might be in a simulation?

ELON MUSK: (00:04:55 – 00:05:37) I once had a dinner at my house with a physicist and a computer scientist, and they’re both leaders in their field. And I asked the question, “What do you think the probability is that we’re in a simulation?” And the physicist said 0%, and the computer scientist said 100% simultaneously. So I guess maybe I should go 50% then. I don’t know.

It’s, I mean, there’s odd things that happen in the simulation where, especially if you’re me, I mean, think about it. If you’re me and you’re like, “Should all these things really be happening? Should I really be making spaceships to go to the moon and Mars?” Like, what the— that doesn’t seem real.

Will Superintelligence Boss Humans Around?

WALTER ISAACSON: (00:05:38 – 00:05:54) And what happens when you have all the intelligence you could possibly want in a society? Will that intelligence, the artificial intelligence, be in charge? Will we sort of become subservient to our new machines?

ELON MUSK: (00:05:56 – 00:06:27) I don’t know about subservient exactly, but will we be able to boss around something that’s thousands or millions of times smarter than us?
