For a serious treatment of this concept read <i>The General</i> series by David Drake and S.M. Sterling.  It's set on a post-fall of interstellar civilization planet where high technology is literally worshiped, but no longer really understood (and all flavored by it being set in thinly disguised Byzantium times, e.g. pay attention to the comments on "vandals" in the second book).  "... save us from the hard rads..." (radiation), something about their souls being saved into ROM (or at least the good parts) ... it's rather interesting.<p>I have a friend who posited a "Church of the Cyber Revelation", based on the idea that that final book of the canonical Bible can be construed to say most anything.
