I agree with wanting to know what others think of as standard skills of human competence, and non-standard, interesting/useful skills of human competence. But I don't see how needing generic levels follows from that. You can know just as much by having a (strength, stamina, math, chemistry, literature, instrumental music, etc.) level system, and with folks giving suggestions for what would be most useful to accomplish life goals generally, without trying to organize those skills into a "human level 1, human level 2" system.
