I'm not entirely sure what you mean by "usual." Like it kinda has a "lesser" implication? In America airplanes were pioneered by two brothers who owned a bicycle shop. Apple was started in some guys garage, the list goes on. It's been shown great things can come from very humble beginnings.

Yeah, and from particularly intelligent and creative individuals. A lot of technological breakthrough would never have been developed if everyone had to says his word, most people being afraid of technology !
