Can you make vim work roughly the same way? Probably you can get pretty close. But how many hours do I have to sink into the config? A lot. And suddenly the PyCharm license is cheap.
And it's exactly the same thing with LLMs. You want hand crafted beautiful code, untainted by AI? You can still do that. But I'm paid to solve problems. I can solve them faster/solve more of them? I get more money.
