Perhaps the progress of Moore’s Law, based on silicon technology, does end at some point rather near in time.
Even in such a dire situation, how much will it matter? It is hard to say. Much computing these days takes place in huge data centers, where heat and energy consumption arguably are bigger problems than processor speed or the cost of memory.
Likewise, end user device preferences arguably are more centered on battery life, weight, device size and aesthetics than raw processing power.
We might be at a point where adapting processing to match the key apps actually will become more important (low power consumption already has become key).
Perhaps processors and architectures, like networks, will be tuned.
Where 19-year battery life is key, processors will support that key goal. If low latency is key, that dimension can be tuned. If peak bandwidth of 10 Gbps is required, that requires a different solution than “100 Mbps whenever you want it.”
And since today’s smartphones already process as fast as supercomputers used to, it is not clear how much “more value” faster processors provide. That has been true for quite some time in the personal computer space, for example.
Faster connections arguably improve experience and capability more than processor speed or locally-resident memory.
Some of us would still bet on human ingenuity to reignite another round of Moore’s Law advances, though. Still, the fact remains: raw processing speed is no longer the chief constraint on application or device value. Instead, it is human creativity which now is the gate.
Maybe processors, architectures and networks will, in the future, be tuned, personalized and customized to fit particular lead applications. If so, Moore’s Law might not be a chief constraint.
