I started a thread maybe a decade ago about where computers were going next. Even then, clock frequency was getting close to the limit. At some point, a high frequency just can't go down a motherboard and all its traces. It seems to combat that problem, they are putting as much of the fast stuff as they can on the CPU die which can handle the higher frequencies. It kinda makes sense really. I still wonder if one day, we buy a board with a chip, memory slots and then a couple ports for video, data storage and user inputs. That's it. In a way, it's not far from that now.
I don't know how long ago it was, but it's quite a long time ago that silicon traces got so slim that that quantum tunnelling is a problem. Are we down to 5nm traces?
Either way, we are down to traces about 5 or 10 atoms wide. At which point electrons can just "magically" quantum jump between tracks. Obviously, this is quite serious before if your ones and noughts consist of just a few electrons, and they can randomly jump about, you're going to get bit errors left right and centre.
