I’m smelling an awful lot of bullshit here. If the power grid (or any other major infrastructure) had a known single point of failure that would cause the entire system to collapse, there would be more than 2 people who know about it, and they certainly wouldn’t be vague-booking it to Lemmy.
This makes more sense than the need to put on pillow cases (which has been my prevailing theory up to this point), but your question about corvids intrigues me. Partially because I’m not entirely certain of what a corvids is.
