I was thinking we're probably on the final straight now, maybe 5-10 years tops? 
I guess it's been prompted by all the stuff about AI recently, and its probable efforts to exterminate humans, which does seem fairly logical. And also reminds me that any technological lifeform, not just humans, would probably be exterminating itself just about now, once the democratization of the means to take life on a vast scale reaches a certain threshold.
You only need a handful of mendacious types, an accident or three, individuals with unstable personalities and so on, to flip the kill switch. I kinda think of it like a natural process for any advancing lifeform that's acquired the means for little people to do big things, that must inevitably happen every time a civilization reaches this point. Not unlike a supernova I suppose. Or an asteroid crashing into a planet. A natural and determinate process.
People say "ah Ceeeffcee, whattabout nuclear weapons - we survived that, we can survive anything!" But nukes are not democratized forms of mass murder. Sure, one nutty person could launch them, but on the whole, you need huge numbers of people working collaboratively to manufacture and maintain nukes. You can't just pop over to your computer and print off a nuke like you (almost) can a virus with synthetic biology. Or like an AI would shortly be able to do.
Maybe this is indeed why we don't really see anything out there? Because all technological life everywhere will always reach this point. I can't see how it would be possible for advancing lifeforms to not reach this point, since democratizing the means to the destruction of life on a vast scale is an inevitable corollary of technological advancement, and so inherently entails an extinction event sooner or later, from something or other somewhere.
