How did you get from type hints to black, not to mention poetry? Seems like you're just complaining about there being a mature ecosystem around Python, and the implicit expectation to use it.
Let's try again:
Python has become a mess. It is no longer a simple productive language to get into like it used to be. Now, you are expected to buy into it's ecosystem, like it is C# or Java.
Well, it is not. It's Python and I am truly sad they are killing it with thousand cuts.
But that's just a symptom of a mature programming language that's used in a variety of complicated scenarios. You don't have to do it all, and no-one is forcing you. You can always write your one-off script without black, flake8, type hinting, or anything of the sort. If it's just your script then no-one will even know.
On the other hand, if you want your code to be part of the larger ecosystem, then you're expected to write it in a conformant way (e.g. pep8 formatting). And that's a good thing!
