Just a handful of current day uP use more CMOS transistors than all the junction transistors produced by any one factory per year.

So, Shockley et al. didn't invent the IGBT either.

JFETs are enormously useful as constant-current devices as well as small
signal switches.

I've got a bunch of tunnel diodes; never found a practical use for them
for me.
