My point is that you can get that with ~1/1000th the compute we spend. The truly useful parts of the internet are a tiny fraction of the tech footprint. There's more net value for us in Wikipedia than there is in ~a trillion dollars of the more vapid tech firms. And it runs on 3m/year in hosting costs.

You are right that China has a food security problem, though. I am, however, assuming that its government isn't blind to it - the country is self-sufficient for high-calorie staples, and wouldn't starve even if all food imports stopped.
