chaos theory is much more important than quantum physics but you never hear about it. ironic because a vast swathe of the science behind computer technology depends on chaos theory principles. cryptography, for example, is rooted in similar mathematics, and the related area of machine learning and AI tech, uses the same sorts of mathematics.
indeed, hash functions are an example of exploiting the asymmetries that are present in chaotic systems. precisely because you can pick a point in a curve, and then work back from there cheaply, but finding it, requires exploring at least half of the field, on average.
hash function is deterministic, but its output is not, because of that asymmetry. that asymmetry is how all unpredictable things are asymmetric in that aspect. you can follow the causal path backwards easily, but tracing it forwards is impossibly expensive.
