On this note; given that it’s suspected that Earth has only a good ~800 million years or so left, that may not even be enough time for another sentient species to emerge with enough time to become technologically sufficient enough to … avert extinction – much less undo some of the damage that we have done. We have to grapple with the idea that if we fail as a species, we’ll be the only and last sentient species on Earth to have emerged. Or as I like to call it: Get filtered, nerd.
