They are identifying with this new powerful technology, because it makes them feel as if they're powerful also.
Like how drivers of monster trucks get a rush from feeling like the power of the machine is their own. Some users of LLMs exhibit the same kind of arrogance of being on the side of a powerful force, like the law enforcement or military. I imagine some gun owners get that rush too. When you take away the gun or the truck, suddenly they feel vulnerable.
I don't think he was calling everybody that is using LLMs a bunch of noobs. I think he was calling the people using LLMs to submit code they don't understand a bunch of noobs. I think if the patches were well reasoned and could be talked about in detail by their submitters, he'd have much less of a complaint.
You shouldn't, unless you're producing a bunch of code you don't understand.
