I was watching a documentary on animal intelligence and it seemed to me that once a species gets to a certain level, individuals start cheating and hiding things from each other. This happens with dolphins and chimps, for example. What humanity has achieved with the internet is the industrialisation of lying, cheating, and faking. An individual's ability to cheat was more or less limited by space (and he had to be convincing). Now a good liar can reach out to millions and he doesn't even have to show his face (and he can reach the credulous easily, so he doesn't even have to be as convincing as before).
