Very interesting times indeed. When I was a kittle kid ---- OK, big fat kid ---- I had a neighbor who built models. Ships mostly. He had some high tech equipment too. A new $4 Case pocket knife and sandpaper. It was amazing what he could whittle out of a piece of pine 2X4 with that knife. In 50 years we might be able to sit in a room full of gizmos and just think of a tank we want and the gizmos will start buzzing and clicking and producing a tank based on our brain waves. I'm gonna think of British stuff.
