HN readers are not average people. elsewhere i see people using AI to write without any blowback. maybe they don't want to ruffle feathers, but they are engaging, whereas i prefer to just skip over AI generated posts.
For her its rarely the specific tells ("not-x-but-y" etc) but rather its bad metaphors and analogies that get her.
I feel a tinge when I see an AI written email that is longer than it needs to be/boring to read but I still need to engage whatever it was they were emailing about anyways.
These spaces are filled with people barely technically literate enough to post and AI is still viewed very negatively
