Actually, I happen to think technophilic life is probably uncommon, and even quite possibly unique--we may be the only such life in our universe. However, I also think that the likelihood that advanced forms would turn rapacious is very small, in keeping with their not being stupid or unenlightened, so it could well be that very many could exist and all of them would exercise the necessary restraint. Also, an occasional rogue civilization that did turn rapacious might be stopped by others before it got too powerful, if there were many others around. (Is this unlikely? Consider that advanced civilizations should be able to estimate the likelihood that a rogue civilization might one day arrive on their doorstep and attack with overwhelming force. One would expect that advanced civilizations in general would carefully consider this problem and maybe work out many possible coping strategies over millions of years. Is it likely that one rogue civilization could defeat all the coping strategies, including civilizations forming confederations for mutual protection? If the civilizations in question were common, I don't think so.) On the other hand, though, if civilizations were common in the universe, one might expect to see at least *some* evidence of them, which we haven't found. So again I don't think they are common. The absence of evidence of them probably means, simply, that they are uncommon (that is to say, it can be taken as evidence of absence) rather than that they do appear frequently but quickly self-destruct. Self-destruction would surely leave some detectable traces, one would think. It isn't ruled out, of course, that civilizations are in fact common but adopt various concealment strategies with almost perfect uniformity--but this kind of argument seems to fly in the face of Occam's razor.
