Morgan Freeman's "Through the Wormhole" show on the Science Channel had an interesting guest a few weeks back: Sims creator Will Wright, who was there to talk about video game games, and gods.
The segment has a simple premise: as computer programs become more advanced, our emotional connection with their creations grow ever stronger. And when they become so advanced that we can't tell what's "real" from what's our own creation, does that make us gods?
Or, as the NASA guy at the end speculates, does that just as easily mean we could be Sims in somebody else's universe? All very high-brow stuff, so if you need grounding, try and work out why a man as rich as Will Wright must be can't seem to get his hands on a pair of cufflinks.
