The story goes like this:
Sometime in the 1940s, Enrico Fermi was talking about the possibility of extra-terrestrial intelligence with some other physicists. They were impressed that our galaxy holds 100 billion stars, that life evolved quickly and progressively on earth, and that an intelligent, exponentially-reproducing species could colonize the galaxy in just a few million years. They reasoned that extra-terrestrial intelligence should be common by now. Fermi listened patiently, then asked simply, "So, where is everybody?". That is, if extra-terrestrial intelligence is common, why haven't we met any bright aliens yet?
This conundrum became known as Fermi's Paradox. The paradox has become more ever more baffling.
Over 150 extrasolar planets have been identified in the last few years, suggesting that life-hospitable planets orbit most stars. Paleontology shows that organic life evolved very quickly after earth's surface cooled and became life-hospitable. Given simple life, evolution shows progressive trends towards larger bodies, brains, and social complexity. Evolutionary psychology reveals several credible paths from simpler social minds to human-level creative intelligence. Yet 40 years of intensive searching for extra-terrestrial intelligence have yielded nothing. No radio signals, no credible spacecraft sightings, no close encounters of any kind.
So, it looks as if there are two possibilities. Perhaps our science over-estimates the likelihood of extra-terrestrial intelligence evolving. Or, perhaps evolved technical intelligence has some deep tendency to be self-limiting, even self-exterminating. 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. Fermi's Paradox became, for a while, a cautionary tale about Cold War geopolitics.
I suggest a different, even darker solution to Fermi's Paradox.
Basically, I think the aliens don't blow themselves up; they just get addicted to computer games. They forget to send radio signals or colonize space because they're too busy with runaway consumerism and virtual-reality narcissism.
They don't need Sentinels to enslave them in a Matrix; they do it to themselves, just as we are doing today.
The fundamental problem is that any evolved mind must pay attention to indirect cues of biological fitness, rather than tracking fitness itself. We don't seek reproductive success directly; we seek tasty foods that tended to promote survival and luscious mates who tended to produce bright, healthy babies. Modern results: fast food and pornography.
Technology is fairly good at controlling external reality to promote our real biological fitness, but it's even better at delivering fake fitness — subjective cues of survival and reproduction, without the real-world effects. Fresh organic fruit juice costs so much more than nutrition-free soda. Having real friends is so much more effort than watching Friends on TV.
Actually colonizing the galaxy would be so much harder than pretending to have done it when filming Star Wars or Serenity.
