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 …
I didn’t say “at all.” Many chemical properties and reactions can be (and routinely are) predicted from approximations, idealizations, and rules of thumb. (These are not, in general reductions.) Some also can be predicted from reductive calculations. Some cannot.

I am not a chemist. OTOH I have worked professionally in molecular modeling, and have multiple publications and patents in the field, so I’m not completely ignorant. My knowledge is quite out of date, so I’ve been interested to learn a bit about the state of art for water models.

Because you don't use "accurately" accurately, you collapse all the relevant distinctions. We can model water on many different levels to differing degrees of accuracy.

Yeah. You did say at all. That was the metaphysical part of your hyperbole.
