at some point it has to stop ? what I mean is when it goes to zero nm will it start like - 90 nm , often wondered what happens at zero. even before i got into bitcoins with just PC's.
The problem is actually how large is an electron. cause down to a certain size, it just simply wont fit through the gate when activated..... Also the smaller the trace the easier it is for an electron to jump lanes and be where its totally not supposed to be. This has been an issue in the development of small size IC for a little bit now.
