I don't even really care if Edison invented anything or not, because he was a douchebag. I don't even care if he ultimately believed AC was dangerous, advocating its use in electric chairs and electrocuting animals publicly is an attempt to use FUD and hysteria to win an argument that he was apparently unable to win by civilized means (and for good reason, because he was wrong).

Also, his aggressive filing of patents doesn't exactly endear me to him either. He held 1,093 patents at his death; did he really invent 1,093 things? He seems to have been an early player in the game of patenting every incremental improvement to everything, which as we see in software hinders rather than promotes "the progress of science and useful art."
