I like to think of DX as true prophecy. In that the original writers would probably vehemently disagree with some of the conclusions that we come to regarding what they meant - and maybe they really just wanted to stuff in as many weird-sounding conspiracy theories as they could - but they were unknowingly tapped into a hyper-awareness of truth that made the game both feel realistic and become prophetic. In other words, if it's based it's accidentally so because that's reality.
