Electrical engineering has transformed from a profession to a ‘trade’ for the simple reason that the problems of electrical engineering at scale are for all intents and purposes solved (reduced to predictable algorithms that we call ‘code’), plus an oversupply of degrees. The other engineering disciplines still vary between profession and trade. I don’t track this discipline any longer but as far as I know, you need to scale up or scale down. Electrical is too ‘human scale’.
