Most people do use LLMs, which is why they have the so-called pessimistic opinions they do.

Judging by most public comments, people are really mediocre at using them. I don't get how it's possible to get such poor results from them.

That's because your usecases were simple and/or small.

Otherwise, you would have known.

Unless you don't have experience and you believe the whole "You are right! it _is_ a and not b" bs...
