      We can’t accurately simulate the physical behavior even of pure water. (Yet; and from other reading about this I’ve done recently, it’s a long way off.) Therefore: Fantasies about simulating brains are fantastical.https://twitter.com/ashleythesmart/status/1032294373382340608 …

      Fair; missing from my tweet are unstated observations about why brains are more difficult than water

      But I've seen the "just physically emulate a whole brain/body" argument enough times, especially among AGI singulatarians, that I would not call it a straw man even if that was the specific target of criticism.

      Really? I don't think I've seen anyone seriously propose trying to simulate a human brain by simulating each atom.

      The argument is usually an in principle one to establish possibility (which does not actually get established), rather than a practical one

      What kind of possibility? It doesn't seem like a bad argument if all you're trying to prove is physical possibility.

          It's a map-territory error. We simulate atomic theory, not atoms. The above shows that water doesn't reduce to atomic theory.

          I feel like saying the observed behavior of water "doesn't reduce" to theory is too strong of a claim if that is to say it wouldn't reduce to even an improved theory (agreed, not with present-day theory.) As for rules vs instances the problem there is more with nonlinearity/chaos
