I think the speed of technology change is approaching the WARP threshold....

Truley it is getting a bit warpy. Heh heh. Technologies march on. Who knows what the actual limits in channel width for MOS and similiar devices will turn out to be from the quantum mechanic models.
And of course the width of the metal and polysilicon runners within the chip's layers that do all the logic interconnects, etc., can only get so small.
Like I mentioned some time last year, back in the early ninetees when an associate lab I was working in at Bell Labs doing fine line processing, one of the physisist I knew showed my why they worried that they soon would approach maximum threshold limit as the transistors approached the lower sub micron channel width, e.g. 1/5 micron.
Then all changed. New processes, better x-ray beam generators and associated methods in making the masks used in the photoresist process etc., where developed along with the actual improvements in making even higher quality silicon ingets, came to be. Result. Everyone start making sub micron parts.
Things just keep marching forward.
