I don't bother with them for prototyping, but I'm a fan of them for anything non-trivial, especially if someone else might read that code someday (e.g. me in a few months). I was code reviewing some Python the other day and I spent far too much time trying to figure out the types, partly because they had a variable which could be a string or a dictionary (erroneously). If they'd have spent a negligible amount of time adding type hints to their code, I would have spotted the bug much, much faster, assuming they didn't find it themselves. I have in my queue of things to talk to my manager about to require type hinting in Python written at my company. We're primarily a Scala shop, and Scala has a very robust static typing system, so I expect it'll be well-received.
(Imagine how much easier it would be reading huge blocks of code on the forum if they're type-hinted and you know mypy passes. I'm probably still too lazy to read code long enough for it to be worth it, but hey.)
