In order for its grandiose ambition of universality to succeed, Facebook would need to be able to do something that every successful yenta can: arbitrage information. It would have to be able to filter out the interesting information from the boring, to know who wants to know what, and who wants what to be known by whom. Can computers carry out such a task? It’s way beyond the ability of current artificial intelligence. But like everything else that computers can’t yet do, it’s only a matter of time.
