>It doesn't require any processing power on your computer, besides the power to record and send your voice. Sure, however this approach has a lot of downsides, such as utter lack of privacy. As we've seen many times historically the pendulum swings between thin and thick clients. Right now the computational power needed to do this kind of processing is very expensive so it's done on server. However, faster hardware will make it possible to do it on personal devices as well. Also worth pointing out that privacy doesn't exist for most people already. The mode of interaction with the computer isn't going to change any of that one way or the other.
