It's the modern equivalent of pasting links to Wikipedia pages without reading them, except that because you're being direct with your question you have a higher confidence that what you're parroting makes some sort of sense.

On the flipside, I'm kind of annoyed by posts cluttering up places like asklemmy that could be trivially answered by asking an AI (or even just a simple search engine). I can understand the opinion-type questions or the ones with a social aspect to them that you can reasonably want an actual human to give you advice on (like this one), but nowadays the purely factual stuff is mostly a solved problem. So when those get asked anyway I'm often sorely tempted to copy and paste an AI answer simply as a https://letmegooglethat.com/ style passive aggressive rebuke.

Fortunately my inner asshole is well chained. I don't release him for such trivialities. :)
