Re: Moore's Law
"At some point the wheels are going to come off the cart and it will probably happen due to increased cost before physics limits."
Probably but there are hard physical limits to this and they are in sight.
Roughly speaking a transistor is about 140 atoms across and historically the oxide layer is about 1/10 that.
If Moores "law" (it's empirical, not derived from first principles) continues then some time in the next 20 years all semiconductor scaling (except the vertical) ends.
And don't even think about the lithography needed to build a "1 atom transistor"
This will make many MBA types on the boards of people like Chipzilla very unhappy, as they discover the truth of Richard Feymann's words that "Against the laws of physics there are no appeals."
