Thats quite a paradigm shift. So it becomes trial and error. Is it because of the use of simulations? I learnt to describe circuits with equations and a pencil, I suppose they just teach the use of SPICE now instead, and the deeper understanding is gone.Yes. And the companies are not encouraging their engineers to work theoretically with the their problems. I was often asked why I had books open instead of just doing measurements.
Now we have AI and soon very few will have to understand how things really work.
