This feels to me that you just don't like people sharing what they've built in general. A lot of these things happen with or without AI.
The UX I expect as a "hacker" is very different from what ordinary people would expect as clients or end users.
Although this site is called 'Hacker News', it doesn't imply that it is building apps for hackers; I think Show HN can also be about the making of things for non-hackers. This site is run by a VC.
I can assure you that when my projects are ready to appear in Show HN, my write-ups will read very differently from this formula.
So what is the right way to write about projects? I've thought about writing something up that I'm building and it probably would have been similar to this structure.
This post makes me lean more toward 'why bother' and perhaps the community loses out on things in this way. Or maybe it is good if I don't write it up.
