Every single language enthusiast says that some of the biggest codebases in the world are whatever their favorite major language is. And here's the thing: it is completely irrelevant whether the codebase is small or large. What counts is what it is like to use and maintain programs.

Python isn't the only language that has poor tooling. C/C++ is even bigger than Python in terms of established code base, and its tooling is nothing short of atrocious.

What helps is people realizing where tooling and production readiness should be. They can learn a lot from Rust and Go.

The it's big so therefore it must be right argument is nonsense. Worse yet: it is nonsense that excuses lack of real improvement.
