The map discusses only risks, not all possible solutions of the Fermi paradox (there will be another map about it). If we are creation of aliens, the question is where they are now - if they are still here, they could terminate us.

If there is a contact, but no intervention, so they will not send us any useful or dangerous knowledges, but just will send "Hi", than there is no risk (but may be opportunity cost as they will not provide important information how prevent risks)
