The end of Moore's Law is a certainty regardless of technology. Something other than CMOS might yield smaller and more power efficient features up to a point, and beyond that point we'd be back where we are today with CMOS. We might as well start dealing with the problem more seriously, because each attempt to kick the can down the road gets more and more expensive.
