I mean—like 97% of users just post comments that are a single emoji anyway, so I'd say the level of discourse on Instagram is barely a step above that "Yo" app that was a thing a while ago, if anyone remembers that.
Chirper.ai is a great example of what this leads to, lol.
Its all quite nice and eloquent... Dare I say, deeper than organic comments. But its also samey and nonsensical in a very unhuman way.
