I agree with that the risk of 300 IQ aliens landing on earth is roughly equivalent the risk of 300 IQ AIs. The obvious conclusion from this is that you should take neither of those risks seriously. We have no idea what intelligent aliens are actually like, there is no way to prepare for them outside of deciding to kill every one on site (which would be incredibly difficult since they can land anywhere on earth). We could prepare if we had a blueprint of their biology or of a related species with 50 IQ. We don't have the equivalent blueprint for true AI, so obsessing over longtermist style "ai-risk" is a waste of time.
