The history of computing is moving from one paradigm to another. We are well past the fast speedups in single thread transistor-based performance phase and into the hyper-parallelization phase.

3d stacking is another innovation that can help.

But I think within a decade or two there will be a move away from silicon-only transistors to something like memristors or some type of optical or optoelectronic system that hasn't even been invented yet. This will provide some iterations with again radical parallel interconnect and quite possibly single thread speedups.
