However, there are thousands/millions of people that are "tweakers". That isn't Jobs' only talent or even his most salient characteristic. (The title of the article is "Steve Job's real genius".)
Did any of the tweakers mentioned in the article start 3 companies and make billions doing it?
I think it is backlash for giving Jobs all the credit for everything, which is a mistake. I agree he didn't "invent" the iPhone, as Obama claimed. He led its development. But it's an equal mistake to say that all he did was tweak things, which the article claims explicitly.
