I agree with your comment. Also, if any expansionist, deadly AGI existed in our galaxy say, 100,000 years ago, it would already have been to Earth and wiped us out. So we kind of can rule out nearby expansionists deadly AGIs (and similar biological aliens). What that actually tells us about the deadlyness of AGIs is an interesting question. It is possible that destruction by AGI (or some other destructive technological event) are usually are fairly localized and so only destroy the civilization that that produced them. Alternatively, we just happen to be in one of the few quantum branches that has not yet been wiped out by an ED-AGI, and we are only here discussing it because of survival bias.
