> The laws of physics dictate what the ultimate limits of a techology are; they do not dictate which technologies you actually choose to use. I never said so, I agree. I'm just stating that I'm confident that in the future, we'll still have tradeoffs. And I'm certain those will include "fast and small, but expensive" vs. "slow and cumbersome, but cheap". We already reached the point where it's a problem that the clock signal on a die spreads so slow that it's a significant problem to increase the clock rate. So we're pushing parallel computing and other solutions, but those come with their own set of trades to make.
