>The idea is a sufficiently advanced AI could simulate.. everything

This is a demonstrably false assumption. Foundational results in chaos theory show that many processes require exponentially more compute to simulate for a linearly longer time period. For such processes, even if every atom in the observable universe was turned into a computer, they could only be simulated for a few seconds or minutes more, due to the nature of exponential growth. This is an incontrovertible mathematical law of the universe, the same way that it's fundamentally impossible to sort an arbitrary array in O(1) time.

The counter-argument to this from the AI crowd would be that it's fundamentally impossible for _us_, with our goopy brains, to understand how to do it. Something that is factorial-orders-of-magnitude smarter and faster than us could figure it out.

Yes, it's a very hand-wavey argument.
