Choices:

Many of these choices will not be a matter for legislatures or courts, but will involve the informal renegotiation of interpersonal relations. This has already begun. For most people the convenience of e-mail, mobile phones and voicemail has proved irresistible, but many have also begun to feel the downside of being constantly in touch. Some feel obliged to respond to messages immediately. Others try to limit the expectations of their boss or family by taking longer to reply, or switching off. As it becomes easier to know where people are at any time, and to communicate with them, the burdens as well as the benefits of being "always on" will become more acute, and private bargains between workmates, friends, lovers, parents and children will have to be struck.

All of this is well considered and fascinating, but it is also a good bet that something - technological, societal, political, whatever - will happen to send the future careening off in another, unforeseen direction entirely.
