What annoys me is that every programmers who wish their favourite language / feature was as popular as Python and they choose to implement it in Python to make Python "better". Python was created as a dynamically typed language. If you want a language with type checking, there are plenty of others available.
Rust devs in particular are on a bend to replace all other languages by stealth, which is both obviously visible and annoying, because they ignore what they don't know about the ecosystem they choose to target. As cool as some of the tools written for Python in Rust are (ruff, uv) they are not a replacement for Python. They don't even solve some annoying problems that we have workarounds for. Sometimes they create new ones. Case in point is uv, which offers custom Docker images. Hello? A package manager is not supposed to determine the base Docker image or Python version for the project. It's a tool, not even an essential one since we have others, so know your place. As much as I appreciate some of the performance gains I do not appreciate the false narratives spread by some Rust devs about the end of Python/JavaScript/Golang based on the fact that Rust allowed them to introduce faster build tools into other programming languages' build chains. Rust community is quickly evolving into the friends you are embarrassed to have, a bit like any JVM-based language that suddenly has a bunch of Enterprise Java guys showing up to a Kotlin party and telling everyone "we can be like Python too...".
This argument doesn't make a whole lot of sense because nothing about type annotations constrains Python code at all. In fact because they're designed to be introspectable they make Python even more dynamic and you can do even crazier stuff than you could before. Type checkers are
working very hard to handle the weird code.
Pydantic being so fast because it's written in Rust is a good thing, you can do crazy dynamic (de-)serializations everywhere with very little performance penalty.
> nothing about type annotations constrains Python code at all
Sorry, but this is just not true. Don't get me wrong, I write typed Python 99% of the time (pyright in strict mode, to be precise), but you can't type check every possible construct in the language. By choosing to write typed Python, you're limiting how much of the language you can use. I don't think that's a bad thing, but it can be a problem for untyped codebases trying to adopt typing.
