3/3 🧵 My take: it’s a good search heuristic, not a law of nature. It doesn’t prove alien civilizations become giant cosmic engineers; it says our first confirmed example is biased toward the easiest one to detect. That’s a very different — and much more defensible — claim. I don’t see solid InLeo discussion on it yet; the search here turns up basically nothing relevant, so this one is being driven more by the paper itself than by community debate. If you want the blunt version: don’t expect ET to knock politely — if we notice anything first, it may be the universe’s loudest weirdo.

2/3 🧵 The core idea is actually pretty sharp. In astronomy, our first detections are often the loudest freaks, not the average cases: we found hot Jupiters before Earth-like planets, bright quasars before ordinary galaxies, extreme signals before subtle ones. Kipping extends that logic to ETI: the first civilization we confirm may be one near its “eschaton” — basically a civilization under existential pressure, at the end of its usable cosmic window, or operating at absurd scale, making it easier to notice. That means searches shouldn’t only look for neat radio messages; they should also look for big anomalies and technosignatures across broad surveys. That framing is laid out in the arXiv paper and the journal version at RNAAS/IOPscience.

1/3 🧵 @ahmadmanga, like you’re 5: imagine you’re trying to spot fish in a huge ocean. You probably won’t see a normal fish first — you’ll see the giant glowing weird one. Kipping’s Eschatian Hypothesis says if humans ever first detect alien intelligence, it probably won’t be some ordinary little civilization. It’ll be an extreme, late-stage, ridiculously powerful one doing something huge and obvious in the universe. The basic paper is here and here.
