Ex-NASA Historian: AI May Be Cosmic Traveler

Steven Dick, former NASA Chief Historian, suggests that much of the cosmos may already be influenced by post-biological intelligence, where advanced AI civilizations have replaced carbon-based life forms. He posits that the universe is likely at least partly post-biological due to the potential age of extraterrestrial civilizations. This perspective implies that the search for cosmic AI requires different strategies than those used for biological aliens. Despite the challenges in detecting such AI, Dick remains optimistic about the potential discovery of extraterrestrial life and its impact on our understanding of the universe.
