@niplav The lightcone would be safe because the aliens clearly don't want there to be big visible changes to the lightcone otherwise we'd see those. Because AI didn't get the aliens, our prior on AI would lean safer, though we have enough direct evidence to swamp that out. It would be nice if they'd do a pivotal action to stop Earth-originating AGI when it looks imminent that left humanity intact, but maybe they'd just have RKVs on a hair trigger.
