I'm missing something in these videos. Is it that the perception we're early implies an implausible scenario because "grabby" (I would just call them expansionist) civilizations would also be cloaking their signals (he seems to gloss over this point)? I.e. "they're out there" we just can't see them, or is he saying that would be implausible because we should have been invaded by now by these expansionist empires, therefore since we haven't we are early? You seem to be saying the theory implies we are early when in the first video I got the impression that is statistically implausible. I guess my main confusion is, if they are grabby, why haven't we been grabbed? edit: watched the second video further, I think I get it a little better now. We are generally early and/or somehow advanced aliens expand quickly, otherwise we'd see signals because the signals would propagate faster than their expansion, whereas if they expand quickly, they'll invade us before we see signals, and dominate a larger portion of visible universe.
