Over at Wired Chris Anderson (he of the “long tail”) talks about how the marginal cost of many commodities is falling to zero. This is very much in line with my comments about Western society becoming more and more like The Culture. (And take a bow, Sir Arthur, for getting it right about telephone costs many years ago.) Anderson also manages to spot that there are some things that will always be in short supply. He mentions time and reputation, but until such time as we build a ringworld he could probably add space. All interesting stuff.
