It’s not right to say that the Copenhagen interpretation means that “only quantum mechanics” is aleatory. First of all, QM describes all physical phenomena so presumably what you meant was “only microscopic phenomena”. But this is not right either, as chaotic dynamical systems send microscopic differences to macroscopic differences and therefore send microscopic aleatory randomness to macroscopic aleatory randomness. It’s possible that there’s even enough chaos in a coin flip to make it aleatorily random.
Yes, most people who are somewhat familiar with quantum physics still massively underestimate how fast these effects propagate.
Even in the Many Worlds model, it’s ridiculous to say that it’s a skill issue to fail to predict things. A successful prediction in such a model doesn’t just mean that you successfully predict “both happen, in some branches or other”, it means that your predictions (which are quantum phenomena like everything else) are perfectly matched with the future measurements in every branch. Under such a model, given some very weak conditions that are easily observed to hold in practice, this is impossible.
A similar objection applies to a Bohmian interpretation.
