Ok the part that I do understand without understanding is that when the chips are too small the light or electrons bleed through the walls of the circuits so there’s interference.
what I don’t understand is how they can get smaller without increasing the bleed.
stronger walls? more finely etched circuits?
Intel among others started including some kind of exotic metal “bead” running diagonal in one of the layers, to bleed off excess electronics. I don’t know how any of this stuff works, I’m still working on how Fred Flintstone can get that car to roll at full speed by just moving his feet a few times.
Faster switches.
I suspect it will involve nanotechnology! Up and coming, all things we use to know as true are changing as we speak.
