'Cos they credit a different guy with making the idea work. Y'know, I'd say "when it's steamboat time...." but his boat steamed rather early (1808!) and it steamed for love: he built the thing so his beautiful, blind girlfriend could write letters! It appears he also invented carbon paper -- instead of the typewriter ribbon.
Sadly, his machine did not survive, though letters written by means of it do; and that's how we know it was real. Can't seem to find images of them online, rather a pity.
--Among other things, this points up a better aspect of dating tech geeks. Just sayin'.
