Wow..
As Metalhead said.. dunno how long it'll take to be implemented. Like speaking into a computer and it writing for you has been around for like 10.. maybe even 15? years now.. but its really not used very much because its so hard to get accurate responses, because the environment can differ so much. So while it may work in a lab, or with the few people testing, getting it to work with masses of people is very hard.
Nonetheless.. watching him do all that stuff on a piece of paper is quite extraordinary. But where does the computing power come from? Do you need a PDA in your pocket or something?
