David Brin has idea after thinking about future making surveillanace unavoidable. The solution is that everybody can spy on everybody else. The problem is that the government and corporations can spy on us, but are immune. I'm not sure if he means it as blueprint or inevitability with the price dropping.
I think he is wrong that everybody spying will help, when everybody discussing online doesn't. But it is useful to think about what world will be like when everybody can surveil.
