Snark omitted, here's an alternate idea of "genius":
The word refers to a kind of spirit or daemon (same root as Genii). Consider the 'daimonion (literally, a "divine something")' of Socrates:

> In ancient Rome, the genius (plural in Latin genii) was the guiding spirit or tutelary deity of a person, family (gens), or place (genius loci).

> Jinn, also Romanized as djinn or Anglicized as genies (with the more broad meaning of spirits or demons, depending on source), are supernatural creatures in early pre-Islamic Arabian and later Islamic mythology and theology.

To be a genius is to be favored or assisted by one of more of these invisible people.
I don't know if they can solve any problem in NP in polynomial time but they can apparently predict winning lottery numbers which suggests to me that there must be something interesting going on from a computational complexity POV.
