Galaxy brain, comment war
Consciousness likely not unique to earthlings, paper says
Scientists say alien minds may be real — commenters say “uh, prove it first”
TLDR: UC Riverside philosophers say consciousness probably isn’t limited to Earth-style life, opening the door to alien minds made from very different stuff. Commenters were split between “obvious” jokes, sharp skepticism about untestable ideas, and a few nerds thrilled by the big question.
A new UC Riverside paper has floated a deliciously brain-bending idea: consciousness might not be an Earth-only club. Philosopher Eric Schwitzgebel and researcher Jeremy Pober argue that thinking and feeling may not require human-style biology at all, which means strange alien beings — and maybe someday even non-biological life — could potentially be conscious too. It’s a big cosmic claim, and the comments wasted zero time turning it into a cage match.
The loudest reaction was a mix of eye-roll skepticism and “well… duh.” One commenter basically compared the whole thing to announcing that water is wet, while another delivered the killer line: “This thing that nobody knows what it is is likely shared by things nobody knows even exist.” Ouch. Others questioned what the point of this kind of research even is if we can’t test it yet, with one doubter asking why we’re talking about alien minds before we’ve even found alien life. That sparked the classic online showdown: philosophy fans saying big questions matter versus critics calling it clickbait dressed up as scholarship.
And because the internet never misses a chance for a joke, the thread also produced comedy gold. One user deadpanned that of all the non-Earthlings they’ve met, exactly zero seemed conscious. Another commenter took the opposite route and dropped a more serious intellectual breadcrumb, pointing readers toward a scientific model that might actually help measure these ideas someday. So yes, the paper is about alien consciousness — but the real show is the comment section, where cosmic wonder met full-strength sarcasm.
Key Points
- •UC Riverside highlighted a new working paper by Eric Schwitzgebel and Jeremy Pober on whether consciousness depends on Earth-like biology.
- •The paper argues that consciousness is likely substrate flexible, meaning it could exist in organisms made of very different materials.
- •The authors do not attempt to define consciousness; they instead assume it is real and ask whether it must be tied to Earth biology.
- •The article says the paper leaves open the possibility that artificial intelligence could be conscious, although the authors do not take a joint firm position on current AI.
- •To support the plausibility of non-Earth consciousness, the authors cite the vast scale of the universe and estimate that at least 1,000 behaviorally sophisticated extraterrestrial civilizations have existed.
