Are you familiar with the Fermi Paradox? The paradox is that the universe appears to be a hospitable place for extra-terrestial life to have emerged, and yet... it hasn't. (So far as the government lets us know, anyway.) If there's not a big coverup, Geoffrey Miller suggests that we might be able to blame the Xbox for alien's failure to visit planet Earth.
It's not as nutty as it sounds. He's saying that "evolved technical intelligence has some deep tendency to be self-limiting." He writes, "After Hiroshima, some suggested that any aliens bright enough to make colonizing space-ships would be bright enough to make thermonuclear bombs, and would use them on each other sooner or later. Perhaps extra-terrestrial intelligence always blows itself up."
How does Hiroshima have any bearing on the Xbox, besides the fact that it's not selling there? Miller continues: "I think the aliens don't blow themselves up; they just get addicted to computer games."
This is a fantastic essay that touches on everything we hold dear: games, fast food, pornography. Are these things killing us? Are games actually holding the entire human race back?
