Here's my thoughts as a 29 year old: of all the things I've ever made in my personal life, the vast majority have ended up abandoned in barely worked on states, and those I have put varying degrees of significant effort in have gone unnoticed. I've never really been able to "enter" a community in a way that felt meaningful to me, either, when I've tried.
I say this not as a complaint, but to explain my perspective on using LLMs for personal projects. Granted, I'm publishing none of them, and not trying to make anyone care about them, so it's not really a response to the article or general discourse here per se, but I thought it bears mentioning anyway.
I'd like to buy into the idea that "doing it yourself" is more meaningful or personally edifying, but I don't get that feeling. I want to get that feeling, but I don't. I've found my private waste-of-time projects using LLMs have been more gratifying than my private waste-of-time projects that don't, and at the end of the day, neither really substantively matter anyway.
Again, this isn't really related to communities per se, but it is an answer why some folks use LLMs for projects/"hobbies".
