> Manufacturing will return to America, where robots will do the manufacturing.

I think this is a really interesting prediction. As opposed to the 20th century trend of industries centralizing to take advantage of economies of scale, the 21st century may see a trend of industries, enabled by robots capable of manufacturing many different products, decentralizing by manufacturing closer to the point-of-sale.

This would be particularly interesting for sectors like clothing, where a small variety of input materials can produce a huge array of output products. Instead of carrying a large stock of clothing in a variety of sizes, each piece could be custom-tailored.
