> in response to identical initial conditions

precisely, mathematically identical to infinite precision .. "yes".

Meanwhile, in the real world we live in it's essentially physically impossible to stage two seperate systems to be identical to such a degree AND it's an important result that some systems, some very simple systems, will have quite different outcomes without that precise degree of impossibly infinitely detailed identical conditions.

See: Lorenz's Butterfly and Smale's Horseshoe Map.

Of course. But that's not relevant to the point I was responding to suggesting that LLMs may lack consciousness because they're deterministic. Chaos wasn't the argument (though that would be a much more interesting one, cf "edge of chaos" literature).
