I've used the example of the bee before. One could exhaustively study a honey bee for centuries and never see in the lone individual any of the behavior of a bee hive. it is just not there, and can not emerge until there are a mass of bees. A single bee lives 6 weeks, so a memory of several years is impossible, but that's how long a hive of individual bees can remember. Humanity is migrating towards its hive mind. Most of what "everybody knows" about us is based on the human individual. Collectively, connected humans will be capable of things we cannot imagine right now. These future phenomenon will rightly seem impossible. What's coming is so unimaginable that the impossibility of wikipedia will recede into outright obviousness.
