As times change things will adapt. I can garentee that you will start seeing plastic shops spring up along with machine shops, etc.. Also people will specialize in wiring harnesses and computer controls. Look at the 50's high end cars. They were extremely complicated and tech savy for the era and who here can't work on a 50's Cadillac with the support of a fourm like this or a shop manuel.
