Via Gertrude Stein (in The Autobiography of Alice B. Toklas), Pablo Picasso explains exactly how the connection between the two works:
…when you make a thing, it is so complicated making it that it is bound to be ugly, but those who do it after you they don’t have to worry about making it and they can make it pretty, and so everybody can like it when the others make it.
It would be impossible to say how much this explains.
