Humans are a plague. Both Aliens and Ai’s of the future will get rid of of us real quick. Maybe keep a few specimens in a zoo? Aliens won’t come personally anyway. VR remote droids or full AI content capture units most likely. It is what we will do one day. Protect or upload the organic mind. Send out 1000s of remote units. Why would you ever risk your organic self. If you can create light year capable tech, you sure as hell have AR and organic/mechanic merge tech. Anybody thinking green men will arrive watched way to much Disnep.
