theoretically solve a problem that would take thousands of years for a regular computer to solve.

And one explanation, a guy named David Deutsch out at Oxford says, well, because it's looking at all the possible values of the bits, there's that many different universes, right?

And it's computing in all of those universes instantaneously.

And then it's bringing back the value that you want at the end.

And that becomes your answer.

So I think we've gone a little bit away from the original question.

Yeah, this subject does tend to take you down many, many different rabbit holes.

And I think your original question was about memory, right?

And how do we know that the memory... So the reason I went down this rabbit hole on the quantum physics stuff and the multiverse, which, by the way, that's the subject of... I wrote a whole second book on simulation theory just for that, which is the simulated multiverse.

Because...

The reason scientists like this multiverse idea is that mathematically you can figure out how the equations work in all these different worlds.

Whereas with the first idea, which is the Copenhagen interpretation,

you have all these possibilities, you have a probability wave, and then suddenly you're down to one.

And nobody can explain that mathematically.

Nobody can say, how does the collapse occur?

There's no little equation you can pop into.

And so that's why it's called the observer effect.

And it's considered a big mystery.

Is it the act of observation?

Is it the act of measurement?
