I read Einstein to say that chaos does not rule the universe. That there is an underlying principle(s).
And in this I think he is yet to be proven wrong.
A matter of interpretaton. Quantum "randomness" is not chaos, it's just a matter of not being able to predict "individual" events at the quantum level. In macro sized numbers (on the order of 10^21 and more particles, things are quite predictable. Sort of like ideal gases. Individual particles are doing the old random walk, but the mass obeys certain laws.
