God only knows, at what point in the development of semi conductors, other, mankind may bottom out.
I was shown through a rough set of quantum mechanic equations by a rather bright physical chemist in my brother's Fine Line Processing Lab associated with my Poly Cell IC. development group at BL, about 1982 or so, at his blackboard, why man would not go beyond the 1 micron channel length in MOS transistors.
The quantum models he was using where apparently slightly flawed. Such a exponential increase in semi conductor physics has occurred since date noted above.
It is rather humbling for me Ernest.

I have never been introduced to the equations.....

My higher level math training was geometry without numbers...otherwise known as Topology (Texas style - my words)...heavy logical reasoning and lots of counter examples....fun stuff .
