Perhaps there is no particular point in knowing what they mean as long as they are useful anyway. Consider, for example, Amazon.com. Amazon neither knows nor cares why John McCreery buys certain books. It suffices that the algorithms that generate those "Readers who have ordered this book have also purchased" suggestions toss up combinations that do, in fact, lead to my purchasing more books. It might be argued that, while we Homo Sapiens are constitutionally incapable of abandoning the search for meaning, the value of what that search discovers is limited. This is the thrust of several forms of mysticism (Zen, for example) and a dark, cyberpunk short story "The Swarm" by Bruce Sterling, whose protagonist is a vast organism, a kind of cosmic jellyfish, that has evolved the ability to temporarily grow sufficient intelligence to wipe out intelligent races that obstruct its expansion but delete it as a waste of energy when no such threat exists. A less apocalyptic perspective, that of General Systems Theory, suggests that the mechanical or statistical models produced by conventional scientific research apply to only a limited set of phenomena--most of what we'd like to know falling into the far larger zone of complexity in which such models fail. New tools like Amazon's algorithms may make it possible to manage complexity with no need for explanation or empathy to understand the patterns that ebb and flow as the data stream pours in.
