I expect these AI and LLM to be, basically, a middle of the bell-curve type producer of code. Just like their other output. Not terrible, not exceptional, just what a Mid could do - only faster.
Not sure what's being marketed, but I expect mediocre.
It does sound condescending. I think the sentiment is important though. Asking someone to be specific can help them think clearly. What’s a nicer way to do that?
I think "Who, specifically, claims that [...]?" comes off as less condescending than "Who claims that [...]? Be specific." just by virtue of the latter using imperative language, which triggers a reflexive "you're not the boss of me" reaction.
