People say this about juniors but I've never seen a junior make some of the bone headed mistakes AI loves to make. Either I'm very lucky or other people have really stupid juniors on their teams lol.
Regardless, personally, there's no comparison between an LLM and a junior; always rather work with a junior.
I've wrote this a few times, but LLM interactions often remind me of my days at Nokia - a lot of the interactions are exactly like what I remember with some of their cheap subcons there.
I even have exactly the same discussion after it messed up, like "My code is working, ignore that failing test, that was always broking, and I definitey didn't break it just now".
