But if it's a simulated reality, then both of these things actually make more sense.

Because on the one hand, you only render that which is seen as a player.

On the other hand, what we're calling multiple universes are just different runs of the simulation.

And so in computer science,

We're always dealing with limitations, so we don't just run an infinite number of anything, because you can't with computer resources.

But if you're playing a game and the AI is trying to figure out what's going to happen, what does it do?

It will try this scenario, it'll try that scenario, it'll try that scenario, and it'll pick the best scenario.

In that case, you cut off the other timelines.

And you go that forward and from there you can simulate different things and figure out which one you might want to do.

So you've got a mechanism for the multiverse as information.

But you don't have to have an infinite number of physical universes per se because when we say this is a universe, all that it means is that currently we're running this program right now.

We could have run another program for a little while and then we can shut that down and we can run this program.

We could even run them on parallel.

Today's laptops have parallel processors, so you can run a whole bunch of things in parallel.

That's what gets to the idea of a quantum computer.

What the heck is that quantum computer doing that it can explore all the 18 quintillion possibilities and come back to us within a few seconds?

well, what does a few seconds mean, right?

A few seconds in our reality, if the program stops,

Like if people are watching this on YouTube, they have a window, but they might have Microsoft Word running.

They might have a spreadsheet.
