That's true. But you have to understand that Rust doesn't complicate things: Things are complicated. The difference between Rust and say, Python, is that Python hides lots of these complexities for you. This can have two sides effects: Performance and unintended consequences (bugs/hard to refactor/etc...)

Rust instead puts all of these complexities in front of you: Deal with it now.

So you have a choice: Deal with it now. Or deal with it later. And Rust has picked the former.
