I would say "debunked" in the sense that quantum mechanics correctly predicts phenomena that don't exist in classical physics, and relies on the idea that quantum particles obey a probability distribution, rather than deterministic mechanics.
Quantum mechanics appears to work so well for these phenomena compared to deterministic mechanics that it's tempting to say that the actual universe is in fact governed by probabilities rather than determinism.
I would argue that all physical models of the universe are just that: Models. We can get asymptotically closer to a perfect description of the universe, but no model can ever tell us the true nature of the underlying system it is describing, just be an arbitrarily good description of it.
The whitespace doesn't bother me at all, but holy hell! Any time I'm trying to understand a Python program/library that's anything above a couple thousand lines of code, I instantly feel a burning hate for dynamic typing.
I love Python for scripting- in large part because of dynamic typing. IMO it's just not a language made for building large infrastructures.
