That's the most accurate term I've heard to describe the situation. I think it could get worse though because when I've seen mediocre people work with mediocre people they generate sub-mediocre solutions through trying to be clever and failing spectacularly at it.
LLMs at the moment feel a bit like a buzwword-throwing dilbertian pointy haired boss. The use terms they heard somewhere and with some luck, they use them in the proper context... but without actually understanding them.
Edit: And yeah, I think I know what you mean. The expectation (or hope) that collaboration of mediocre people results in some above-average end by means of some magical synergy effect very rarely works in real life.
