You can argue this any numbers of ways:
- As you say, if we really need exponentially increasing numbers of CPUs, then silicon limitations will require more sockets and thus more latency.
- If the limits are economic, then most people will buy as large a system as makes economic sense for their workload. This has historically resulted in very many very cheap small systems and a very few very expensive large systems, effectively limiting system size more severely than the pure technical limits.
- There is the question of whether the limits are good or bad, in other words, do you favor increased CPU counts on the one hand or existing software on the other?
