I moved into the language full-time in 2010 and it's now 2021.
The packaging ecosystem is still a burning dumpster fire, the performance is still hot garbage and the whole approach to asyncio makes me want to bang my head against a wall.
Tthe latest additions in Python 3.10 have me shaking my head. I love pattern matching (Yes, Scala fanboy detected) but shoving them into Python just seems....poorly thought out.
I really hope to move away from the language in the long-term because I feel like it's a bad thing when I would rather work in Java or C++ than Python. For me it feels like Java and C++ took a look at themselves at the end of the 2000s and said "Okay, we need to sort something out, what we're doing now is not winning any hearts" while Python did also did some introspection and decided "Meh, let's just keep throwing mud at the wall until something sticks". It's one of the few languages I've worked with which seems to be actively getting worse every year, which is kinda sad :-/
