At some point, Moore's law will break down.

When you zap things with light to build quantum computers, you're hacking existing systems. You're hijacking the computation that's already happening in the universe, just like a hacker takes over someone else's computer.

It's also a reasonable scientific program to look at the dynamics of the standard model and to try to prove from that dynamics that it is computationally capable.

At some point, Moore's law will break down.

Yes, I am a quantum mechanic! Those darn quantum computers break all the time.

Thinking of the universe as a computer is controversial.

I have not proved that the universe is, in fact, a digital computer and that it's capable of performing universal computation, but it's plausible that it is.
