How are you coming to the conclusion that "median human" is "basically achieved"? Current AI has no means of understanding and synthesizing new ideas the way a human would. It's all generative.

A "median human" can run a web search and report back on what they found without making stuff up, something I've yet to find an LLM capable of doing reliably.

Your "original definition" was always meaningless. A "Hello, World!" program is equally capable in most jobs as the median human. On the other hand, if the benchmark is what the median human can reasonably become (a professional with decades of experience), we are still far from there.
