Talking about Thomas Edison, who was so driven in his work that he completely neglected his wife and children and ended up working 114 hours in a week, Greg agreed he was a genius and one of the great men of all time but said he was also a sonofabitch: "every great person in the world, I think, is a sonofabitch, because you cannot excel in things in a world that is set up to discriminate without being a sonofabitch and discriminating in some way. Those who do it best are probably the ones who have fucked up the most people".
