For those who aren’t aware, PCB design used to be an automated task, done by software with minor tweaks. The thing is, complexity had a positive payoff, so soon we had trained technicians doing layout. Right now most PCB layout require so much technical knowledge most people working in layout are engineers with masters degree.

Of course there’s also a lot of cheap electronics where complexity doesn’t payoff and cutting development cost it’s what matters, but it’s not most of the market.

As long as you keep learning and improving, you are likely to see an increase of demand, not a decrease, although the job will be quite different.
