Regular chips are about tapped out.
We are rapidly approaching the point that we will be super cooling

There is only so much you can do to shorten the data path.
They are just making them wider. (multiple processors, wider buses)

There's talk of stacking vertical substrates also. However the big
future opportunities are in developing better software that can take
advantage of massively parallel processors like IBM's Watson. Those
machines are very esoteric and expensive with today's hardware but
it's only a matter of time before they can stamp them out like jelly
beans. Present software systems have to be highly customized to take
advantage of that kind of power and more generic solutions are needed.
If quantum computers ever become a reality, and they probably will,
they will all will be massively parallel. The possibility of
simulating human thought at blindingly fast speeds is somewhere out
there on the horizon for better or worse, along with instant and
accurate language translation, monitoring millions of security cameras
simultaneously, accurate long range weather forecasting, and a whole
bunch of stuff that hasn't even been thought of yet. Computer
applications are already designing new computer hardware and have been
for some time. What we need now are applications that design and
produce new software.
