It could turn into a very long technical discussion.
The basic thing to appreciate is that chaotic behavior
is far from random behavior. In fact it typically has
long-range order that can be exploited. There is at
least one published chaotic bit generator that has not
yet (so far as I know) been shown to be distinguishable
from a uniform-random bit generator, but since it is
based on a simple deterministic formula one should feel
uneasy about what developments the future might bring.
(The simple formula is offset by a potentially
unbounded amount of internal state; otherwise cracking
the generator would be trivial.)
