Seems there are at least three Rust-based competitors for type checkers in Python now (Microsoft, Facebook, Astral), and of course there's still mypy.

Pls forgive my ignorance, but how is Typescript (a superset of Javascript) used to type-check Python?
just like the Python compiler/interpreter is written in C.
Yes. If you want runtime validation of data you’re taking in people recommended pydantic. If you’re looking for runtime validation within your own code I’ve seen people use beartype, though to be honest I don’t personally understand the value added from it
...or Marshmallow, which allows one to do many complex validations in a relatively trivial manner.
On one hand, I feel like I've been in a coma since covid because I've just been coasting along with Marshmallow and jsonschema, but on the other hand it's like a lot of the major advances have been in the past couple years. Apparently pydantic got a big version update in 2023? And now all these competing static type checkers?
Close, Microsoft’s type checker Pyright is Typescript. Its still faster than mypy for me though.
