But remember that we have a lot of real estate to work with. This kind of thin film printing is already being used to make amorphic photovoltaic cells for energy production. The technology to make batteries and displays and processors and memories is well along at Rolltronics. And if for some reason those guys stumble, somebody else will make this happen. Take two more orders of magnitude out of the cost of computing and the game is completely changed.

Every country has a network. Hundreds of millions of cheap computers working together as massively parallel computers lead to scientific advances we can't even imagine. And the old-line companies like Intel and AMD, which are currently fighting over which is the superior obsolete semiconductor company, well, those outfits go out of business.
