I have taken a long time to write this because I have been trying to think of something that would sound more sincere and less embarrassing. But there is only one wish worth making, as I see it, only one thing to ask for: let everyone have enough. Begin with their material needs. Give them enough food, enough shelter, enough money, enough art. Connect them all to the Internet. Then see to their softer requirements: Enough love. Enough friends. Enough sex. A complete wikipedia in all of their languages.
I do not have to make a trade because it is a wish but perhaps I, perversely, want to make one anyway: that no one will have too much more than enough. That many of us will have much, much less.
Mike Meginnis does this sort of thing.
