Maybe the Aliens Are Addicted To Computer Games 496
Hugh Pickens writes "Geoffrey Miller has an interesting hypothesis in Seed Magazine that explains Fermi's Paradox — why 40 years of intensive searching for extraterrestrial intelligence have yielded nothing: no radio signals, no credible spacecraft sightings, no close encounters of any kind. All the aliens are busy playing computer games. The aliens 'forget to send radio signals or colonize space because they're too busy with runaway consumerism and virtual-reality narcissism,' writes Miller. He says the fundamental problem is that an evolved mind must pay attention to indirect cues of biological fitness, rather than tracking fitness itself, and that although evolution favors brains that tend to maximize fitness (as measured by numbers of great-grandkids), no brain has capacity enough to do so under every possible circumstance. 'The result is that we don't seek reproductive success directly; we seek tasty foods that have tended to promote survival, and luscious mates who have tended to produce bright, healthy babies. The modern result? Fast food and pornography,' writes Miller. 'Once they turn inwards to chase their shiny pennies of pleasure, they lose the cosmic plot.' Miller adds that most bright alien species probably go extinct gradually, allocating more time and resources to their pleasures, and less to their children, until they eventually die out."

That's one of the most ridiculous hypotheses I've ever read. Sure, it is possible, Sure, everything we know about aliens is based on speculations that don't go against our knowledge. But most speculations at least seem plausible and match the only example of an advanced civilization we know of.
And this single example has shown us a few things for which I would be surprised if they don't apply universally. The first is that no matter what the general population are, there would always be deviations and a small percentage of people who are different is enough to affect world-wide matters. The second is that if these different people don't exist or are unable to push the rest of the society like we do, the whole population would probably still be in the caves, because most of our progress depended on them.
Well, the last one seems plausible, though. However, I thought that the possibility that all aliens are still in the caves was already considered, and thus this story brings nothing new to us.
I don't think there's one reason for it all, though.
1. While I want to believe that life is abundant in the universe, complex life as ours might turn out to be rare.
2. For four billion years all life here was essentially living in the caves. We created our civilization in a wink lasting the mere fifty thousand years because homo sapiens somehow managed to look outside of the box by chance. Sure, being intelligent was an evolutionary advantage for the billions of years that the homo genus survived, so we didn't come out of nowhere, but there's still no guarantee that this happens often in the universe. We might be one of the few advanced civilizations.
3. What makes us think we can hear them? Have they developed the radio? Do they use broadcasts? What if they use encryption making the signals indistinguishable from noise? Why would they care to send signals to us? Maybe some of them "know" that there's a little chance that there's someone out there?

Miller thinks that our indulgence in entertainment is what is limiting our reproduction, and he's been flogging this nonsense for years, ignoring the stunningly obvious and well documented fact that lower birth rates are caused by global urbanization, combined with reliable birth control methods and low infant mortality rates (if all your children live, you don't need to have as many).

Since we know that 1 is not a useful sample size, of course, we know that's false; but you might as well say anything, since we have no basis for comparison.
It's particularly telling that we are not the only creatures on this planet with a well-developed brain. Our form factor is our primary distinguishing characteristic.

It seems that the arrangement of eyes, nose, and mouth on the head are biologically convenient; food doesn't fall into the nose, nor snot into the eyes. Quadrupeds are naturally less agile than bipeds, which indeed is likely why one sprang from the other on this planet, so bipedal life is highly likely. So where I am going with all of this is that by the available evidence, Klingons are at least as likely as some insectoids.

All pack animals act as a single organism in some sense, but they have a hard time passing learned information between members, so the pack as a whole doesn't learn. With sumbolic language, humans overcame that, allowing concepts of any abstraction level be passed between people. The human pack began to learn, and as it learned it became better at utilizing resources, causing it to grow, which in turn made it smarter. That's why culture really took of after the invention of agriculture: the number of people, and thus their collective brain mass, exploded.
The problem humanity solved was not how to make its members more intelligent, it was how to exceed the practical size and complexity limits of the nervous system a single organism can carry with it.

A factor of 200 really isn't very large.

If you can sustain 0.01g for long periods (which ion drives should soon be able to do) the it will take you a year to get up to 0.1C, but that's not a huge amount of time in comparison to the time it takes to travel from one star to another at that speed.
Even a short trip will be a few centuries, so one year for accelerating and one for braking isn't really relevant, especially if you can use solar energy at both ends and only carry a small amount of propellant that you accelerate to very high speeds. Special relativity actually helps with reaction drives, if you can accelerate the propellant to a nontrivial fraction of the speed of light (ion drives work on the same general principle as particle accelerators, so this is not entirely unreasonable).
Of course, I said technologically feasible, not economically feasible. A craft capable of crossing interstellar distances and doing something useful on arrival could probably be built today, but it would take the entire output of several industrial nations with no hope of any payback. By the time it arrived, it would be obsolete; even a 1% improvement in acceleration would get a second craft to the destination years earlier.
The craft that you cited are chemical rockets. These have a much lower power to mass ratio than an ion drive.

Because colonization was usually driven by wanting some resources which are abbundant over there, and are in short supply over here. Even if sometimes that meant "living space".

And if they are, how come they'd reject _only_ space colonization in favour of sitting and playing games, but not the other forms of work, including making those games?

And if c really is the speed limit, and space being that big, maybe nobody is interested in investing now in a ship which would return with the goods in 1000 years. Just because they don't even know which resources will actually sell that far in the future. Less than 200 years ago, aluminium was more expensive than silver or even gold, so I guess if we sent a ship to establish a colony and mine the most expensive stuff we can get there, it would have been aluminium. Then almost over night a new process was invented for producing it, and price fell like a rock. Or as little as 100 years away, coal was the fuel of superpower navies, and wars and willy-waving games were waged over access to it and to coaling stations. Then it all moved to oil, and now to nuclear reactors.
Or maybe they just don't need the extra space, and hence the colonies. Everywhere on Earth where we got sanitation, antibiotics, etc, population stopped growing and in fact started to decline.

Basically a realistic enough VR environment, thanks to our ability do immerse in it and forget that it's not real, can fulfill all the psychological needs of an individual, more so even than reality since it has fewer barriers and does not suffer from the limitations of normal societal structures (in human society there are only a limited number of positions of a given type, for example Village Chief, but in a VR environment you can use NPCs to create as many virtual societies as you want and as such as many slots of a given type as you want).
There are quite a number of natural limitations to a scenario where all mankind lives in VR:
- Natural selection would remove from the genetic pool those that spent all their time in VR, since they wouldn't reproduce.
- Physical needs would still have to be catered for. This means that things still have to be produced (like food). The VR environments, being targetted at satisfying the individual would be highly unproductive, so full automated means of production would have to exist, and they would need to be fully fed from some for of free energy.
- As long as there are multiple nations, unless ALL of them "went into VR" at the same time, the ones that didn't would simply march their armies into the land of ones that did and take over.
That said, for exploration of the unknow to stop or slow significantly, all that it takes is for the Explorer types amongst us - the same kind of people that 3 or 4 centuries ago would be jumping into boats and travelling to unexplored lands, and the same kind that nowadays would drive us to explorer space - to fulfill their drive to explore in VR environments which one miht argue already happens in part. It's thus quite possible that this will keep Human Society in the period of stagnation with regards to expanding our physical borders of knowledge in which it currently is. In the extreme, having lost all our drive to physically go out and explore, humans could turn their backs to space forever.
That such a scenario could occur in alien societies is not beyond the realm of possibility. However, there are other drivers for exploration (conquest, material wealth, overcrowding, maybe even religious reasons) and the idea that all alien societies will sooner or later fall to the trap of "satiation of the need to explore by VR environments" is far fetched.
Then again one might also argue that the causal relation is actually the reverse:
- Human Society being in a period of stagnation with regards to expanding our physical borders of knowledge is not caused by Explorer types finding saciety in VR environments but instead said Explorer types are driven to "find their fix" in VR environments because we are currently not expanding our physical borders of knowledge.

A civilization able to harness any sort of practical near-light or faster than light space travel, radio waves would likely also have totally unknown communication methods.
A civilization bound to physics we understand would have no use with radio waves for interstellar communication. It requires a tremendous amount of power, virtually all of which is wasted. Not to mention the noise and interference with shorter range communication that radio is good for. The only use an interstellar civilization would have for sending radio waves over interstellar distances would be specifically for the purpose of communication with unknown civilizations.
Given our current level of technology, we do have a device which is fairly close to ideal for interstellar communication. Lasers. Far more of the energy you pump into the beam will arrive at the destination, requiring far less power than a radio transmitter. One obvious side effect of this is that any interstellar communication going on out there would be invisible unless directed at us.

It's sort of like being in the middle of a giant warehouse, taking two steps forward and declaring that your intensive searching has revealed no "outside world." Perhaps we need to wait a few more decades, centuries, or millennium for the signals to reach us.
2. Perhaps the signals have already passed us. Maybe, sometime during the building of the pyramids, radio signals from an alien world were passing by us. The humans of the time would have had no way of knowing that proof of alien life was right in front of them. By the time SETI began searching for life, the alien signals stopped either due to the civilization dying out or due to the aliens moving on to technology that "leaked" less. We've used radio for a little over a century and are already switching to technologies that don't involve tossing unencrypted signals in the air all over the place. Perhaps there's only a 1 or 2 century window from when a civilization first uses radio to when they move to a different, more undetectable, technology.
3. Perhaps we've seen it but didn't recognize it. Who says that we'd actually recognize an alien signal. If I gave you some network monitoring tools and sent a few hundred streams of data down the pipe, most of which was random but one of which was encoded information, would you be able to tell the random from the information? Even if you didn't know the encoding scheme or what kind of information you were dealing with? I'd bet that it would be tough to do and that's dealing with human-created encryption schemes. Add an alien intelligence to the mix and the difficulty would skyrocket.

Going back to #1's warehouse analogy, it'd be like searching a giant warehouse, opening one box and declaring the item to not be in the warehouse because it wasn't in the first box you opened.
