Lots of articles have been written about practical difficulties with the EU cookie law, but something much more serious was worrying me as I explored the topic. Do you remember Asimov's three laws of robotics? Do no harm to humans, obey humans, and preserve yourself, in that order. While the laws have weaknesses that underlie the plot of Asimov's novels, they are fundamentally right in one thing. They don't care what the robots can or cannot do. They only care why robots do things. They focus on ethics, not mechanics, of actions.
