What would happen if someone builds a device that can replicate anything, incl. itself? If it can replicate itself, soon there would be millions of them and they would be basically free ("hey, can i have another one?") and whatever they replicate would also be basically free ("how about a swap: my 3000 DVD players for your 2000 MP3 players?")
