People are forgetting the following things which may be more useful for home computing:
Non planar geometries (functional silicon has been made like this) - eliminates many issues of having a massive CPU die because the edges of the chip aren't miles away, so the clock pulse will still diffuse to the entire chip within a clock cycle, and the latency of everything will be reduced.
Graphene (maybe less than a decade away) - should allow higher clock rates (because maximum temperature is higher) and maybe a slightly smaller manufacturing process.
Biological computing (we've hooked up worm brains to LEDs and made them flash or something like that) - May turn out to be great for massively parallel and pattern recognition tasks, and shouldn't be hugely expensive if it can ever be done at a useful level.
Molecular/Protein mechanical computing (CEO of Intel mentioned this as a viable possibility) - may be better than electricity, may be completely useless.
Using photons instead of electrons - I've not heard much about this in recent years, which would imply people have decided that quantum effects would take over, and stop your photon based logic gates from interacting with the photons reliably.
There's not necessarily nothing between silicon and Quantum
