Mr Jarvis like all public media spokespersons are talking their book. If privacy dies they have more to write about. Investigative journalism becomes easier. I would like to think the human species can transform into a thronging common sentience. One giant being made up of all living people (and through their blogs, dead people too). But evolution will prevent such an outcome, because for all those nice collaborative vegetarians out there, there will be an omnivore who will devour them at will and we will end up with a group of oligarchs that exploit transparency rather than join it. A bit like certain media empires today. A show of hands please, who wants to be Rupert Murdoch?
