Users typically don't read code, developers (of the software) do.

If it's not worth reading something where the writer didn't take the time to write it, by extension that means nobody read the code.

Which means nobody understands it, beyond the external behaviour they've tested.

I'd have some issues with using such software, at least where reliability matters. Blackbox testing only gets you so far.

But I guess as opposed to other types of writing, developers _do_ read generated code. At least as soon as something goes wrong.

Developers do not in fact tend to read all the software they use. I have never once looked at the code for jq, nor would I ever want to (the worst thing I could learn about that contraption is that the code is beautiful, and then live out the rest of my days conflicted about my feelings about it). This "developers read code" thing is just special pleading.
You're a user of jq in the sense of the comment you're replying to, not a developer. The developer is the developer _of jq_, not developers in general.
We're talking about Show HN here.
But you read your coworkers PRs. I decided this week I wouldn't read/correct the AIgen doc and unit tests from 3 of my coworkers today, because else I would never be able to work. They produce twice as much poor output in 10 time the number of line change, that's too much.
Right, I'm not arguing developers don't read their own code or their teammates code or anything that merges to main in a repo they're responsible for. Just that the "it's only worth reading if someone took the time to actually write it" objection doesn't meaningfully apply to code in Show HN's --- there's no expectation that code gets read at all. That's why moderation is so at pains to ensure there's some way people can play with whatever it is being shown ("sign up pages can't be Show HN's").
