Or maybe that's because it's a worthwhile and viable policy objective.
Pardon me for being skeptical, but could you provide a source for that claim?
That's a pretty bold claim you're making. Let's have a look at some actual numbers, shall we?
This chart indicates that not only are we keeping up with Moore's law, for the past 2-3 years we've actually moved ahead of where we'd expect to be. And the graph doesn't even include AMD's R800 graphics chips, which have even higher transistor densities than RV770/GT200.
