I think its a direct reflection of the fact that most people really prefer to go-go-go and not spend the time up-front thinking about what their project even is, why it matters and is it worth dedicated resources toward it. The abandonment usually reflects the answer - no it was not worth it.

LLMs amplify this behaviour.

There is a difference between a project that is eventually abandoned out of annoyance because you couldn't accomplish what you wanted and a project that gets a day or two of attention and then gets aborted because you figured out it wasn't worth it or got interested in something else. I think the parent comment is talking about the former and I'm responding to that, while you're talking about the latter.
