Corvette test drive

At what point did a mechanic become a technician? Was this away for the dealerships to glamorize their business. No malice intended just curious
Could a "Technician" today be able to change points and condenser and set dwell especially on a duel point distributor? I'm sure there are a few but then again they wouldn't have a computer to diagnose the problem. No offense of course but some guys are just replacement artists.
