Madness!!!! I can just see a board designer, saying "the next job is
doing
a bridge". get real. Well reality passed the snots by a long time ago.

You'll find that once you get past a certain level, there isn't actually
much difference between engineering disciplines. It is basically
mathematics. There's not much difference in the mathematic contortions
required to design a bridge to resist wind loads as compared with designing
any other control system (mechanical, electrical or electronic).

It's basically all solving differential equations to the highest order you
need. Obviously, there is a certain amount of specialisation into fields,
but this is only about 20-30% of the game. About 70-80% is identical between
disciplines.
