Of course. When I say "biocentrism" I'm specifically referring to the idea that of all the planets in the universe, abiogenesis only occurred on Earth. So if we did find another island of life, biocentrism would be dead. We would know that Earth wasn't not "uniquely unique" in that respect. I guess the goal of the article was to assert that because the idea of "centrism" has proven so consistently wrong over historical time, that the current intellectually tenable "centrism's" are likely to also be proven false, at least IMO. To what degree life and intelligence emerges in the universe, I don't know, but I'm quite confident this isn't the only region of space-time where it has occurred.Even if there were life on some far-away planet system, it would still be pretty rare, right?
