> Ten years ago I'd go to robotics conferences and it would not be unusual for me to be the only person in the room who knew that control theory was a thing. This is mind-blowing to me. When I thought I might have a reason to develop some robotics technology, the very first thing I did was to get a control theory book, on the off chance that I was really going to do this in the future. In fact, I think this explains why the product I think could be made does not exist yet.
