I think that's fair from Primo.
Creativity is a very dangerous thing, the balancing act between confidence and arrogance; standing your ground and being stubborn.
You can't survive on your own in the creative field (don't ask how, but I know). You need peers, that is peole who are as creative and as open as you are, to give you advise and critique and help you up your game.
Lucas had Spielberg who had Scorcese who had Coppola. Needless to say 70's is the goledn age of film.
Most of the times you don't even have to be in direct contact for the influence to happen.
Nas is too creative for his own good. In this current rap climate, who's really qualified to tell him what to do. Or inspire him to lift his game. No rappers, no producers, that's why his albums are A+ lyrics, A+ message A+ concepts, but the beats, hooks even sequencing are subpar. He really needs a creative counterpart, not hottest producer now, not a label suit, not these subpar rappers. He needs a Madlib.
Incidentally, that is the problem with the South African Hip Hop scene...but I'll weigh on it some other time.
