Very interresting read. I didn't thought that ground 'bots were used so intensively by the military tough but then, I'm no military man myself.
It well seems that we attaining a technological turning point, at last concerning robotising. Bipedal bots in 20 years? I'd like to see that! Tough I do not foresee much day-to-day practical use right now. Mowing down darn lawn is about the best use I could have from a robot right now, other than that...
Again, we all here will be much older before they become a standard of living tough.
Again, a good read.
