And of course we can't know. But whenever I truly think about or hear being listed potential outcomes in singularity-type discussions, like cosmic engineering and interstellar travel and immortality and other large-scale events that would make any sapient being sit up and take notice that something really seems to be happening in that section of the galaxy, I start to consider John's first possibility. In the broad strokes. Why isn't there some evidence elsewhere -- Von Neumann probes, as Avante said, or radio signals? If a singularity is inevitable, and even if it isn't and just desirable for some technologically-inclined species, shouldn't such goings on be apparent to us if it has happened elsewhere? Especially if it has happened frequently?</div>
<div><br></div><div>I mentioned Robert Charles Wilson's novel Spin the other day in a post. Have you read that? In it, Von Neumann machines sent out from advancing civilizations all over the universe have "teamed up" and formed a vast cloud AI that then begin to interfere in the affairs of their makers. In Isamov's Foundation Trilogy and Herbert's Dune, human beings are the progentitors of cosmic engineering and the first technologically-proficient species to emerge in the universe. What I was saying, I guess, as ridiculous as the last sounds, it seems more probable than the first to me. Because the only evidence we have seems to support that. Or at least supports that there seems to be no evidence of a large-scale singularity and superior machine-based civilization elsewhere that is suddenly messing around in the universe dramatically enough for others to notice. A third possibility is that other civilzations are advancing at roughly the same rate as we are, and are on the verge of their own explosions into the universe around them but still struggling with biological imperatives and resultant limitations. A fourth is that even very advanced civilizations are limited by vast distances and lack of resources so that they barely make a dent in the universe around them, no matter how smart or powerfully they can engineer themselves. </div>
<div><br></div><div>There may be a million other possibilities, none of which I am smart enough to come up with. Carl Sagan came up with a number of reasons in Contact why there could be advanced species capable of revealing itself to us via its technology but chose not to, but everyone of them was based on human ethical standards. </div>
<div><br></div><div>Surely we'd be able to recognize the technology of a post-singularity civilization before we'd recognize their ethical motivations?</div><div><br></div><div>I'm pretty new at this, and just trying to understand. So I may be covering very old ground here, but this thought has been troubling me for many years. Since I was a kid in fact. </div>
