I agree a brute force effort like you're likely referencing would take tremendously more power than an AGI, but the premise is basically that AGIs would be able to make both the hardware and the simulation itself hyper efficient. There are likely ways to run a simulation that give you everything you need without simulating the entirety of a physical body for a given test. If we're stress testing a type of concrete, we don't have to build an entire building to test only the concrete. We know how the concrete interacts with the building.

> Plus, fundamentally in nature there are many "chaotic" processes that are impossible to accurately simulate more than a few seconds ahead due to the amount of computation required growing exponentially with simulation duration.

I'm not sure what you're referencing here. I don't anticipate a future where an AGI can predict what every single cell in your body will do after taking a pill.
