That assumes that interstellar travel is possible. Physically, economically, socially, there’s a lot of boxes to check for near-light extrasolar expansion (let alone FTL, which probably is impossible)
I think the easy solution to the Fermi Paradox is that we’re stuck in our fish bowl and so is everyone else.
I mean, yeah. But there’s so many clones and time travelers and Multiple Man copies running around already that I don’t think TOAA or whoever is keeping track.
