Pre LLM's I used to get this from managers, but what they would do was quote verbatim from stack overflow or some random blog post of how to do a thing with no to little context or understanding of what they were talking about. And it always turned out to be from amongst the top three results from some popular search engine when describing the complex problem the company/team was facing.
Yes, stupid and lazy people will be stupid and lazy.
AI is just another tool they can use to be stupid and lazy while pretending to contribute.
Slightly different though if it comes from a manager, since his ass is on the line if the project isn't going well. Well, it should be on the line although they usually manage to make a random dev responsible for their mess even they had no say in it.
