We are at the start of a revolution. I remember when computers first became personal. People asked what would I do with that? " You could do taxes" OK what else does it do? Then the Internet, graphics, WiFi and so many other technologies advances the computers to where we are today. That is where we are with robots. They are primitive. They do little. But it will change exponentially. One day they will be every where and will be in your workplace. I predict within 7 years they will be walking in the malls and down your street.
History is a good teacher.
