From my perspective, the fact that so much of computing has consolidated around a language that cannot support even the most rudimentary code completion or static analysis tools is deeply unfortunate. As a result of Python's mass adoption, uncountable thousands of hours of developer time have been wasted hunting down bugs that would have been caught by tooling in any statically-typed language.

Unless Python can fix this, by adopting static typing, it's not entirely fit for purpose in the ecosystem niche it has come to dominate. Replacing Python with a better language would be a net productivity boon for developers and scientists almost everywhere.
