I think that that's not valid.

But tell me what you think.

I guess – so I'm trying to map on the externalist point of view you just put forward to – I think I was, again, insufficiently clear in talking about the attitudes of my fellow cosmologists.

They all say I'm not a Boltzmann brain.

But the conclusion from that I'm realizing as I'm thinking more carefully is a little bit different.

Someone like Rafael Busso, former guest on the podcast, would say –

If I lived in this universe that has eternal fluctuations, I should be literally floating out there in empty space as a minimal conscious creature.

But the data tell me I am not.

Therefore, that cosmological scenario is ruled out.

And I need to find a cosmological scenario without such fluctuations.

Yeah.

Yeah, but I think it's a little bit – I want to say you're giving them too much credit for sophistication.

They're not saying I have data about an apple in front of me that I don't believe.

They're saying it's kind of a – it stems from this belief.

Nick Bostrom-like attitude that we should think of ourselves as typical observers in the universe.

And they say a typical observer in the universe doesn't see a desk or an apple in front of them.

They look around and they see empty space because they just fluctuated randomly into existence.

I don't see that.

Right.

Yeah, I mean, I don't even think we need to have a stance on favoring lots of observers or high frequencies or not.
