I agree in general, but defining an appropriate target seems intractable at the moment. Perhaps it is something the AIs will have to define for themselves.

I think real intelligences are working with myriad such targets, but an adversarial environment seems essential for developing intelligence along this axis.

I do think if there's a path to AGI from current efforts it will be through game play, but that could just be the impressionable kid who watched Wargames in the 80s speaking through me.
