In High School I was taught vacuum tube technology (mhos and transconductance, grid bias and thermionic emission) and maybe I haven't used it much, but it gives me an understanding of the 'big picture' that freshly graduated techies these days do not have.
They're still used in high-power RF transmitters.
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
