If your solution to any problem includes the phrase "If everyone would just X" then you don't have a real solution, because there is no future where "everyone will just X"
"Everyone just needs to learn not to trust the AI so readily"
That isn't a real solution. Everyone will not just become more skeptical and better at critical thinking
"If only everyone would just do X" where X is a thing that has a positive benefit is unrealistic.
"If only people would learn not to do Y" where Y is a thing which actively hurts them and which they can learn the negative consequences over time feels a whole lot less impossible to me.
If your co-worker pulls this crap, tell them not to. Complain about it in performance reviews. Replace them with someone who writes good code.
