And then their body is rescued and they're brought to the hospital and there's this whole thing where you extract the blood and warm the blood in a machine and you're passing it back in. And people end up freezing.

fine like they actually come back to life really from being frozen i've never heard of that happening that's incredible here's one to link in the show notes i'll send you a lancet article is a medical journal about a woman who was a young doctor who this happened to on a skiing trip and yeah she's probably fine she's practicing medicine now and so on but she was dead she was actually dead and frozen and she was brought back this happens not infrequently in theory she's a few minutes younger than her actual age it's not bad

Not bad. So everything about cryogenics should work in theory. The problem is simply that how do you freeze things fast enough so that you don't get ice crystals and you get ice crystals that tears the cell membranes and blah, blah. So there's some stuff to be worked out there. But yeah, I think freezing people and sending them on space travel is certainly a possibility.

What's interesting about that theory is that Descartes was at least one of the first people to talk about this thing. How do I know I'm not brain in a vat being stimulated by scientists so that I think I'm sitting in this sunny living room talking with Jordan and so on? And people have worked on better and better versions of this.

And obviously, in the modern computer era, this became, how do I know I'm not a computer simulation? Well, what's been so weird to watch just over the last decade, really, is... how extraordinary things are becoming. For example, with generative AI, people are using this in VR now to create whole VR worlds instantly. Like, hey, I want a 15th century whatever with a castle.

And this just gets created the same way you would create an image, but a whole 3D VR world. And we're just in 2025. I mean, just imagine what things are going to be in 2045 or something. So the point is, it becomes more and more plausible to say, God, we know we can make extraordinary simulations. Why not? And all it requires is imagining that maybe...

Just imagine our civilization a thousand years from now, they might be running these sims. And of course, this could be recursive all the way down.
