> But this is different from if we can simulate some amount reality at all, which I think is possible, and I use that to demonstrate why I think computers can contain human like intelligence in theory.

In what kind of theory, though?

In mathematical theory you can use a googol watts. In "things you can do in this universe" theory you can't use a googol watts.

I understand the argument of taking a small accurate simulation as a basis point and extrapolating to a larger simulation. But if you're stuck with exponential complexity, then that extrapolation doesn't work. The demonstration of simulating 5 particles becomes useless. Even if you can massively simplify it, if you can't eliminate the exponential cost you're screwed.

I agree with most of what you are saying; it absolutely applies to physical questions. Whether or not quantum computing can be practical depends on our ability to fight off decoherence in more and more qubits.

But I'm more of a software guy, so it feels fair to ask if Turing completeness enough to simulate reality, and therefore human-like intelligence?

If so, what shortcuts can we take to avoid simulating "everything"?
