"With little or no human involvement, come up with paradigm-shifting, Nobel-caliber scientific discoveries."
Indeed far above the capabilities of almost all humans. I agree we should have a separate category for this. "ASGI" is still a bit unintuitive, imho. Maybe Artificial Excellent Intelligence.
With AGI explicitly meaning matching average humans, I would say that we really have already reached AGI. I can't think of any intelligence-only task where I'd think an average human would do significantly better than frontier AI provided with correct context.
