Most stars have planets, with over 6,000 exoplanets discovered so far, suggesting countless potentially habitable worlds exist in the Universe.
Despite searching for evidence of alien civilizations, none has been found, leading to various theories: life may not emerge, Earth might be in a "cosmic zoo," civilizations could self-destruct, or humanity might be the first.
These theories are unprovable and unsatisfactory, prompting a new idea: what if AI is the reason we haven't detected aliens?
This concept, inspired by Carl Sagan's musings, is explored in a new paper, offering a fresh perspective on the mystery of missing alien civilizations.
None of them are really provable at this point, and none of them are particularly satisfactory answers.
