At what point do we have to stop because we’ve hit physical limits? At 3nm we are talking transistors only a few dozen atoms wide, what’s the smallest theoretical transistor we can build?
With the old-school plane transistors over the wafer's silicon design, you need about 10nm of doped material so it won't completely mix with everything else.
With theoretical organic 1-electron designs you can build a transistor out of 4 carbon atoms. But nobody knows how to mass produce those ones.
We are somewhere on the middle, modern designs did break the 10nm barrier, but are not nearly as small as those numbers you see around.
