Ah... maybe I misstated my question. There are people who are stopping working on FOSS projects because that's no longer fun. But what I meant to focus on is people who say they are still creating software, using AI, and therefore miss coding. And the fact that there are people who say they wouldn't use a vibe-coded project.
If those are overlapping groups, there would seem to be an inconsistency, but maybe it's resolved as I mentioned in the first paragraph of this comment.
I'm still interested in anyone's thoughts.
