Are the aliens merely sleeping?

Here is another attempt to crack the Fermi paradox, relying on low time preference and Knut Wicksell’s wine parable:

“While it is possible for a civilization to cool down parts of itself to any low temperature,” the authors write, that, too, requires work. So it wouldn’t make sense for a civilization looking to maximize its computational capacity to waste energy on the process. As Sandberg and Cirkovic elaborate in a blog post, it’s more likely that such artificial life would be in a protected sleep mode today, ready to wake up in colder futures.

If such aliens exist, they’re in luck. The universe appears to be cooling down on its own. Over the next trillions of years, as it continues to expand and the formation of new stars slows, the background radiation will reduce to practically zero. Under those conditions, Sandberg and Cirkovic explain, this kind of artificial life would get “tremendously more done.” Tremendous isn’t an understatement, either. The researchers calculate that by employing such a strategy, they could achieve up to 1030 times more than if done today.

In other words, now is an inefficient time for getting things done.  That is from Robert Hart at Slate.

(Why?)
