A much more concrete example is cloud computing. Granted, computers don't "think," but it's a close enough analogy.
You must always keep in mind that there is no magic "cloud"- only concrete machines that other people own and keep hidden from you. People who might have very different ideas than you on such matters, as for example, privacy rights.
