Voice-Activated/Operated?
That is the silliest idea I have heard since the last time I heard it. Even after years of research, development and use they can't even get dictation software to work 100% accurately. We have a long way to go before there is enough processing power packed into a small enough, fast enough package to make voice control a feasible control interface and even then it won't be practical. Who wants to work in a cube farm where everyone is talking at their computers for their entire shift? Too distracting.
