And I find it really fun to think about.

Right.

So I think, you know, another reason I don't I don't really think infinity is like a real construct is I really I'm a big fan of Nick Giz and he's a physicist that's kind of arguing that real numbers aren't real.

And what he means by that is like if you want to compute a real number and like, you know, we use real numbers like, you know, like they they require infinite precision to to compute all the digits.

And, you know, you're assuming a lot of resource for a universe built on real numbers because basically it means anything that you look at, you can look at with infinite resolution.

And it's probably the case, especially if you think the universe is constructed or even if you believe in a simulation argument, that there has to be a granularity there because the universe has to do these things in finite time with finite resource.

There isn't evidence that there's infinite time or infinite resource in our universe.

And therefore, like if you want something to actually be physically real, the universe has to be able to implement it.

The universe cannot implement infinity in finite time.

It just can't do it.

Yeah.

And I think time is finite.

I think time is a resource.

And I think time is, you know, part of the mechanism that the universe is actually constructing itself.

The universe is constructing itself from moment to moment.

And, you know, and we persist over a certain set of moments.

But yeah, this is why I said I'm a presentist.

And I don't even know if I agree with myself on this.

Like I disagree with myself on a lot of things and I might change my mind tomorrow.

But it's like the idea only the present exists.
