Is there any indication that it’s possible to build subatomic size transistors? Last I checked the data, transistors are already only a few atoms in size (silicon and carbon atoms are somewhere in the 0.3nm range), and it was a widely held opinion that it would stop at that if not much sooner. That would keep Moore’s law alive for a bit longer at best but the end does seem in sight.

Even considering all of that the economics seem to have already stagnated in cost for performance.[1]
