Lone Wolves...
attract other Lone Wolves. Once they are in the same room the stars align, the magic happens, and we put out kick ass products or whatever.
Then we split, so as not to tear each other's heads off cause of too much alphaness in the room. Or when it seems it is all getting to "corporate", and therefore uninteresting.
Woz and Jobs were never meant to last forever, just as iterations of Justice League and Avengers will never last forever. We may fade into obscurity or the void or [insert here], but at least we did it our way under our rules and had a freakin awesome time breaking the mold.
