Perhaps in some cases. But I had a relative who was a genius at business, however he attempted to work on his car once and spent a few hours turning a socket before realizing that he needed to use a 1/2 inch instead of a 1" inch socket. He was turning that socket forever before asking someone who was familiar with working on cars what the problem was. He never did get the concept and decided not to deal with that type of handy work any longer. He's not alone. There are tons of people out there who just don't understand how to work/build stuff. The end result is the same, people love to fly a plane. Some build the planes they fly while other's can't or don't want to build them. I love to eat sushi, but that doesn't mean I can or want to prepare it. And I won't tell people I made the sushi I purchased already prepared.
