This sort of thing will be useful for lots of peaceful purposes too. True telepresence, for instance, a la Surrogates. Fire and rescue workers equipped with something like this will be able to save others without having to risk their own lives. Astronauts could remain safely in orbiting ships, sending down only robotic suits, possibly to environments like that of Mercury, where it would be all but impossible to protect a human body.

Then there are non-android uses, like simply controlling machinery or computers without need of physical contact. Repetitive Stress Injury could become a thing of the past when all you have to do is think about hitting the keys. I imagine you’d be able to “type” a whole lot faster that way too.

And of course, it will pave the way for the inevitable merging of mind and machine.
