Latent Space: The AI Engineer Podcast · After LLMs: Spatial Intelligence and World Models — Fei-Fei Li & Justin Johnson, World Labs · 25 Nov 2025 podcast

It's actually unfair.

Right.

But then the reason it's obvious to us is because we are internally mapping it back to some three dimensional representation of the world that we're familiar with.

I mean, even even if you do, like there there's sort of a pragmatic thing where people use language and people want to interact with systems using language.

Even pragmatically, it's useful to build systems and build products and build models that let people talk to them.

So I don't see that going away.

I think there's a sort of intellectual curiosity of of saying how like intellectually, how much could you build a model that that only uses vision or only uses spatial intelligence?

I don't know that that would be practically useful, but

But I think it'd be an interesting intellectual or academic exercise to see how far you could push that.

Yeah, I I mean like there's another engine I mean you actually don't even need to be doing AI to answer that question.

You could discover aliens and see what kind of physics they have.

Right.

And they might have a tool.

They face

so what do you so I mean, but that is a really interesting question, right?

Like, is our knowledge of the universe and our understanding of physics, is it constrained in some way by our own cognition or by the path dependence of our own technological evolution?

And one way to sort of and and like do an experiment, like you almost want to do an experiment and say, like, if we were to rerun human civilization again, would we come up with the same physics in the same order?

And I don't think that's a very practical solu uh practical experiment to run.

My my guess is it probably probably won't.
