Picasso and Jobs: the favorite examples of the "throw the doors open" crowd. 

Ofcourse this crowd conveniently leaves out the fact that such artists did not feed on the cultural differences between their mother land and France. They fed on the so-called "non-existent" French culture.  Original creativity is overrated. Picasso said "Every child is an artists. The problem is how to remain an artist once we grow up".

You forgot Brancusi.
