Ever since the 1960's we've had AIs that beat aspects of human intelligence. These days AIs are "godlike intelligence" at boardgames, visual recognition, programming (know any programmer, no matter how good, that can get a fluid dynamics simulation from scratch in 2 minutes?), reading comprehension, understanding humans (both speed and accuracy), ... and so on and so forth), and every few years something gets added to the list (I particularly enjoyed robotic ping pong. And it's "not really" AI (kind of, convnets certainly work best, but yes you can code it by hand if you control the environment). But you're not winning even a single ping pong game, it's just not happening)

Every time people find something they're still superior at and declare whatever that is the most important thing in the universe.

Perhaps a more useful definition of AGI would be an intelligence good enough that it can go from raw materials to a working AI at least as good as itself ...
