There are 15 electronic gizmo type items on this page, being sold from America’s Technology Store. 13 of the 15 you now always have in your pocket.

How much would an iPhone have cost in 1991?

Innovation blindness, I’ve long argued, is a key obstacle to sound economic and policy thinking. And this is a perfect example. When we make policy based on today’s technology, we don’t just operate mildly sub-optimally. No, we often close off entire pathways to amazing innovation.

cost 150 trillion of today's dollars: one and a half times today's global annual producttaken up a hundred-story square building 300 meters high, and 3 kilometers long and widedrawn 150 terawatts of power—30 times the world's current generating capacity
