The Times Online has an interesting analysis article from Anatole Kaletsky (link found via Daily Summit). I hear echoes of Julian Simon, particularly in the fifth paragraph: "The experience of the past two centuries suggests that the generations of the future will be infinitely cleverer than we are. They will devise solutions to their problems with an ingenuity that we cannot begin to imagine today. It is not just lazy and selfish to leave the solution of many long-term problems to future generations; it is rational."
