I need to do more research on the topic, but I think this is a little bit of an illusion.
A chaotic system, K, is one in which the probability of measuring a "high order digit" (eg., 10,000) in the output is sensitive to a "low order digit" in the input (eg., 0.000001).
Something like: P(log_o K(state) | log_i state) < 1 where o >> i
It seems true that a non-chaotic deterministic function, eg., f(t) can be created such that "K(state) is bounded by f(approximation)".
Eg., K(state) is the weather, and f(approximation) is the climate model. Or K(state) is the behaviour of gas particles, and f(approximation) is the gases temperature model. Or K(state) is the changing matter distribution of the universe, and f(approximation) is the stable gravitational field model in our solar system.
f() is long-run predictable -- but K() isnt. But we know f() fails in the long-run -- K() does eventually change against the predictions of our model f().
Eg., over long periods of time, the climate changes; the non-ideal gasses may spontaneously condense; the sun "explodes".
f() is only ever a locally/apparently deterministic approximation.
