Hmm. "God's quarantine regulations" in action? According to "Rare Earth" you may need a lot of Goldilocks stuff to work out for life to exist. But I'd imagine something unicellular could get going in a lot of environments that wouldn't support multicellular life, and multicellular could get going in lots of places that wouldn't support technologically advanced species, and so on. But a centauri is a triple star and barnard's is an M type dwarf IIRC, neither may be as suitable as a single G or K type. Maybe Tau Ceti would be a better bet, admittedly a bit further to go (5 light years further IIRC!) But those AIs are patient. Also there's the possibility of getting small space ships that don't require life support up to relativistic speeds with antimatter or a light sail. I'd be happy to wait 50 years for news from another star, while 500 is pushing it a bit. (Shame Leonardo didn't invent a generation starship...)
