You'd have a point if there were any changes that are being introduced and putting developers on a straight-jacket. But I don't see this tension at all.
What is recent on Python3 that makes it hostile to hobbyists? The new features are optional, it's not like Python is forcing people to adopt mypy.

Python has become a very complex language [0], and the complexity continues to increase. IMO it's too much for people who only write code for, say, a few hours a week.

I hope Python isn't becoming a "choose your own subset" language like C++.
The tweet shows a clear list of features (aside from the walrus operator) that are "complex" because they deal with inherit complexity. People who write code only for a few hours a week don't need to deal with asyncio or parallel programming, typing, cython, etc, etc.
The point about different frameworks and ecossytem is a strawman. Yes, it's large. No, it doesn't mean that is complex. No, you don't need to know all of it.

You are implying that are what is being added to the language have overlapping functionality. You really need a better argument than a FUD-y tweet to justify your concerns.
