I realized only later that my statement needed an extra qualification: entrepreneurship is killing (non-entrepreneurship related) genius
Certainly Ron Popeil is some kind of genius...George Foreman too. But I'd challenge anyone to hand me a business model that could be formed around General Relativity! If we had demanded a business plan from Einstein before we let him continue working on his ideas, he'd probably have died a patent clerk.
I upmodded you because I think your post is worthwhile but I think you're conflating entreprenurship with short-sighted greed.
Entrepreneurship and genius are just different aspects of the same thing: solving problems in new ways, more often than not by challenging the percieved rules of the game.
