I mean, I think you're always on the edge of it, but I think what is amazing about being a scientist and trying to do things rigorously is it keeps your sanity. So I think if I wasn't a theoretical physicist, I would be probably not sane. But what it forces you to do is hold the fire, like you have to hold yourself to the fire of like,

these abstractions in my mind have to really correspond to reality. And I have to really test that all the time. And so I love building new abstractions and I love going to those like incredibly creative, you know, spaces that people don't see as part of the way that we understand the world now.

But ultimately I have to make sure that whatever I'm pulling from that space is something that's really usable and really like relates to the world outside of me. That's what science is.

Yeah. So the issue is we evolve perception to see reality a certain way, right? So for us, space is really important and time feels fleeting. And I had a really wonderful mentor, Paul Davies, most of my career. And Paul's amazing because he gives these like little seed thought experiments all the time.

Like, you know, something he used to ask me all the time was when I was a postdoc, this is kind of a random tangent, but was like, you know, how much of the universe could be converted into technology if you were thinking about like, you know, long-term futures and stuff like that. And it's like a weird thought experiment, but like there's a lot of deep things there.

And I do think a lot about the fact that We're really limited in our interactions with reality by the particular architectures that we evolved. And so we're not seeing everything. And in fact, our technology tells us this all the time because it allows us to see the world in new ways by basically allowing us to perceive the world in ways that we couldn't otherwise.

And so what I'm getting at with this is I think that living objects are actually huge. Like they're some of the biggest structures in the universe, but but they are not big in space, they are big in time. And we actually can't resolve that feature. We don't interact with it on a regular basis.
