Moore's law is more of an implementation detail than anything else. Nobody really cares about transistors. What we all care about is computational density, computational efficiency, and exponential progress. Thus the interesting metrics are something like flops/m^3 and flops/Watt. The cool thing about Moore's law is that by just shrinking transistors we would get both smaller and more energy efficient chips.<p>I think that economical forces will continue to drive progress, and probably exponential progress like we've enjoyed in the past, for at least another decade. Probably several.<p>The way this is going to happen is through a paradigm shift. To the layman this seems weird, but to anyone in the business this should be expected. We've already been through quite a few. The first computing devices were mechanical, then they were based on electrical relays, then came the vacuum tubes and finally we entered the era of the transistor. We can argue about what the next paradigm will be, but I have no doubt there will be one. And soon.
