The culture that language maintains is rather hostile to maintainable development, easier to just switch to Rust and just write better code by default.
Lack of types, lack of static analysis, lack of ... well, lack of everything Python doesn't provide and fights users on costs too much developer time. It is a net negative to continue pouring time and money into anything Python-based.
The sole exclusion I've seen to my social circle is those working at companies that don't directly do ML, but provide drivers/hardware/supporting software to ML people in academia, and have to try to fix their cursed shit for them.
Also, fwiw, there is no reason why Triton is Python. I dislike Triton for a lot of reasons, but its just a matmul kernel DSL, there is nothing inherent in it that has to be, or benefits from, being Python.... it takes DSL in, outputs shader text out, then has the vendor's API run it (ie, CUDA, ROCm, etc). It, too, would benefit from becoming Rust.
Yet it was created for Python. Someone took that effort and did it. No one took that effort in Rust. End of the story of crab's superiority.
Python community is constantly creating new, great, highly usable packages that become de facto industry standards, and maintain old ones for years, creating tutorials, trainings and docs. Commercial vendors ship Python APIs to their proprietary solutions. Whereas Rust community is going through forums and social media telling them that they should use Rust instead, or that they "cheated" because those libraries are really C/C++ libraries (and BTW those should be done in Rust as well, because safety).
