It's pretty remarkable that things have continued to function since my 17 years with Python alone have seen things like:
- Compilers becoming available on all OSs - Linux becoming a thing - Laptops becoming common - Smartphones - Web-based email clients
As I have said a few times in comments on this thread, it's fine to feel like there's room for improvement, but trying to "stick it" to Python and its packaging ecosystem in some way for not being perfect is pointless for you and demotivating for those who are actually in a position to try to make things better for you (and even if you aren't a Python user you should care to some extent about it as Instagram runs on Python and thus it is helping to deliver you those cat photos while you're stuck at home ).
Second, there is the python foundation, which funds people to work on areas of python. This should be a priority, and can be done by paid contributors.
The fragmented ecosystem is one of the main complaints about Python packaging today. And that's really tricky, because the main way the open source world knows to solve problems is to create new tools, and that doesn't help when the problem is 'too many tools'.
