I'll side with Krugman here; yours is a nanosanta scenario where all consumer
goods are as cheap as wheat. Krugman forsees progress in the cost of ordinary
consumer goods, but the same sort of progress we have seen. So I'd bet he
wouldn't expect a nanosanta tech to be available in a century (if ever). He
might be wrong about that, but if so it's not because of bad economics.
