"There are new morays and new norms that are being created. Technology always frightens us. We did not discuss a legal right to privacy in this nation until 1890 and it was because of the invention of the Kodak camera. Louis Brandeis and his co-author of the Harvard Law Review were frightened because Mr Warren's daughter's wedding had been photographed and the penny press was a way to expand that and we got very scared (see 1890 paper here). And what they came back to in the end, they couldn't find a right to privacy in the US Constitution. We have a right to publicness, it's the First Amendment, but not really a right to privacy. And whenever technology has come it involves change, and change unsettles us and we get scared of of that and then we look for all the bad things that can happen and we worry about it and we should because we should guard against cruelty and bad things that can happen. But we shouldn't manage our whole world around that."
