> my nano-microchip

Are you quoting some really obscure science-fiction story?

BTW, wouldn't a nano-micro-something be a femto-something?

Nano-what? "Microchip" isn't a material ... But silicon is, and you can have as many nano-silicon microchips you want!

The gates on these chips are 22 nanometers. "microchips" have been measured in nanometers for a while.

Silicon is here to stay for the foreseeable future, and for a very simple reason. While we have many advanced possibilities with germanium or carbon nano-tubes or other such advanced processes, silicon is still the cheapest by such a magnitude that it wins out in performance per dollar.

Blank CDs were pretty expensive at one point.

I remember (early 80's) when a box of 10 HP floppy disks was £100

I remember (mid-80s) when my extremely noisy 20MB SCSI hard drive cost me just under $1000.

I'm not saying it will always be that way, but rather there is a large gap so, barring incredible breakthroughs, silicon's got at least a decade or so left.

Why couldn't we have incredible breakthroughs tomorrow? Well, we could, but they've been working on non-silicon tech for at least thirty years now- and we are still using silicon.
