Actually I directly countered it, as far back as before this thread started, on other threads. I did it first on the origins of science fiction "firsts" thread that I started. I still stand by it and see nothing new to change my mind on it.
You countered it the same way you did just now: by posting links to more technologies you assumed would continue to grow exponentially.
You DO realize, of course, that nanotube-based microchips could very well bring about the flattening curve whose existence you continue to deny; depending on the expense of actually producing those nanotubes and the difficulty of reducing their size and/or increasing their speed, we could already be approaching that point of diminishing returns where further advancement fails to yield an increase in performance.
