I… I'm not sure how to feel about this one. I think my main problem, and I'm sorry if I'm being dumb here, but… Is there anything anomalous about the continued survival of Earth? Most of the piece is explaining what's happening to other places, but there isn't really a focus on actual description of the phenomenon. In fact, anything besides the first sentence isn't really describing the phenomenon per se.
What I understood from the piece is that every known civilization has destroyed itself except ours but that doesn't feel anomalous. In fact, the most anomalous part of this is that these other places exist, I suppose. There may not have been close calls, but… Hmm. I dunno, maybe I would be more on board with this idea if it was explored better. I don't really feel like what you're describing here is all that 'unique' despite being portrayed as such. Unless this is a ploy by the Foundation to pass the idea as anomalous to avert nuclear war? But that isn't implied either so I'm leaning towards the former.
Overall… Yeah, I don't really get the idea of what you're describing as anomalous is anomalous at all, and that may be because of a lack of exploration of why it is anomalous. Like, yeah, we're told it is, but there doesn't feel like there is a reason why it's considered as such. Like, sure, all civs known by the Foundation are dead, but they've also only discovered 11 to 15 of them. If there is a risk that we could blow ourselves up, does that not mean we're not actually anomalous then? Or rather, that the anomaly is the almost 100% chance that the extinction of a civilization is through nuclear warfare, and not necessarily that our survival in special in some way?
Maybe I'm being a bit pedantic, but the execution of this piece doesn't really leaves me with a satisfied answer about what even the anomaly is about, really. The description is short, it explains the concept briefly and then doesn't really does much past that, and what it does only left me confused so… Yeah, apologies, but it's a downvote from me. It may be harsh, and the idea here is interesting, but I don't think it was well executed.
