I guess I'm optimistic that in thirty to fifty years or so we'll basically
know enough about this. We already know quite a bit.

I'm also optimistic that we'll be able to compile such simulations by
many orders of magnitude. Yes, we'll have to simulate in great detail
to make sure we understand how each local thing works. But once we
understand that, and we can see what details matter and what don't, then
we should be able to throw away most of the irrelevant detail and simulate
at a higher level of abstraction.
