Though, aren't there also plenty of other mechanisms that affect it? For example increasing speed of manufacturing procedures and improving knowledge about how to design complex systems. The end seems to be extremely dense blocks or spheres of highly optimized computation substrate, where each atom sits very precisely at the right place. But the state of the art is merely a few layers of crude photo-lithography. Imagine nanobots being programmed to move atoms around to assemble 3D circuits at the 10nm scale. I think this is where we are heading, and this will likely grant a couple of decades of continuing exponential progress. And by then our computation power will be insane. An equivalent of the simplest human brain models will likely fit into pea.
