Fair point on 1, although I personally view that as extrapolation from an incomplete theory. But perhaps I have not read enough of the evidence for that bound.

I think you underestimate the complexity of systems with more than a handful of interacting particles. Yes, you can extrapolate with what we have but I think the answers you get are likely to be totally wrong outside of a very controlled regime. People simulating large scale interaction have to make a lot of simplifying assumptions, which need to be tuned to the problem at hand to be effective. Non-equilibrium statistical mechanics is poorly understood.
- eru 2y agoThey make a lot of simplifying assumptions, because they don't just care about computability, but about finishing runs of their simulations before the heatdeath of the universe. Our discussion was about the computability only, wasn't it?
- bubblyworld 2y agoThat's true, it was a weak point. I'll have to think about why this unsettles me, thanks for the food for thought.
