Some of us have been here longer than AI. "To be intellectually stimulated" would be the why, which there used to be more of prior to the frontpage becoming riddled with AI slop. "HN is for conversation between humans" as the guidelines say, and though the guidelines imply that's towards comments, I'd prefer it to be towards submissions too, for the same reasons it was added for comments.

I'm already at the point of "the reward/effort of HN is getting pretty low", but the question is, where to leave for?
