You can't participate in agriculture or redesign of aircraft...

You can't participate in agriculture or redesign of aircraft for making them safer if you know nothing about it. So, whenever a person says 'will I be participating in the new world?' Only in areas that you can participate it. Areas that you have competence in. I'm not talking about self confidence, I'm talking about the ability to solve problems. Electrical, chemical, technical. I don't know of any other kind of problem.
