A.I. Threat or Opportunity

I always liked to do something with my hands, and once in grades 4-5, I decided to build a robot. It was made of plywood, and almost my height. The robot was equipped with a vibration motor (brushes for clothes as his feet plus eccentric motors), so that he could move. His eyes were light bulbs with a conical reflector made from a tin can. He raised his hand when you came closer to him, thanks to a photo diode reacting to changes in lighting which was built into his chest.
