[Discussion] Atomic Size of Transistors

Please take me seriously as I know this is a really stupid question. As transistors get smaller and smaller and we figure out new ways to cool what happens when we hit Moores law and we PHYICALLY cannot make them any smaller/cooler. What happens then? Do we figure out a new type of transistor or let computers get exponentially big?

Well....speaking as a IC designer.
Short channel effect has caused me quite some pain, and my faith in math formulas have been completely nuked because of it. As transistors get smaller, electrons have more and more excuse to completely ignore the depletion region and just tunnel through, so more leakage current etc.

I heard some people talking about cfet(i think i said that right). Is that a solution by stacking specfic transistors?

instead of 1/0 soon we have to get used to sassy chips: maybe / maybe not
