Software engineering would have been a higher quality profession of python had never gotten into any production project. Now we need to patch over the mess by adding mypy but we could have used a language with explicit types right from the start and it would have saved a lot of bugs in the category of 'every typo is a new variable'. This so-called evolution is basically creating messes everywhere and code bases that only use one language and one build system are the most understandable ones. Also, once upon a time a programming language was a thing in which you could write anything of your fancy. If that is the case 'multiple programming languages' is itself somewhat of a weird thing.
