Furthermore a ai does not compute a physics model any more than a brain does, so the criticism does not apply.
The point is that the universe can do things that functions cannot. If your only tool is functions (only thing that algorithms can compute), then you will necessarily be unable to handle all possibilities (by which point, I question your intelligence).
But even so, it's confusing to phrase intelligence in terms of non-determinism. It's easy to come up with a non-deterministic answer to an arbitrary question. It's hard to come up with a correct answer to an arbitrary question. If unpredictability is a component of sound reasoning, it's because we humans are so bad at reasoning.
The problem is not that, "my answer must be 'unpredictable'", but, "the actual answer may not be computable" (and so, no algorithm may ever derive it).
