Yeah, I have my doubts about the claim. I forgot what I read way back when as an intro book, but I suspect it was more like a month in my case, if that. But I remember having been surprised at various points that there was an undo (C-_), and a clipboard (C-y to paste) including a history (M-y). So yeah, I guess it depends on the scope.
Maybe it's a hyperbole? Dunno, doesn't really read that way.
