Earlier quoted context omitted.
I have no idea why this "AGI is not even well defined" meme gained so much traction recently. AGI is something that can do everything better than humans. Write a novel, seduce someone, prove a theorem, fix a pipe, whatever. And it's clear right now we don't have it.
Given your definition what's the difference between AGI and superintelligence? AGI should at least match, not surpass humans in every cognitive task.
Nothing in AGI implies "surpass humans in every cognitive task".
Not even "match in every cognitive task" is really required. There are humans that by definition have "general intelligence" that still don't match other humans "in every cognitive task", just in some.
Why should AGI need to match ALL humans in EVERY congitive task then? An AGI just needs to be as good as an average (or even slightly below average) human, in human-like cognition.
