> The top 10% is even better with LLMs, they know much more and they are more productive. But the rest have just resulted to turning in clear slop with no care.

This is interesting, I'm noticing something similar (even taking LLMs out of the equation). I don't teach, but I've been coaching students for math competitions, and I feel like there's a pattern where the top few% is significantly stronger than, say, 10 years ago, but the median is weaker. Not sure why, or whether this is even real to begin with.
