robotic jeeps and cargo helicopters

I remember seeing stuff like this in the movies when I was a kid. Then, once I got into the Air Force, I used to wonder why we didn't automate more stuff. Now, I wouldn't want to fly in an airplane as a passenger with a robot at the controls, but there are tons of applications where human beings aren't aboard. I'm all for taking soldiers away from danger as much as possible. But I have to admit it's a little hard to wrap my head around the idea of combat happening in a room full of kids sitting in comfortable armchairs playing "video games". Anyone ever read the book, ENDER'S GAME? Look like it's almost here...
