It's great to see a respected Harvard scientist push the envelope on extraterrestrial life. Avi Loeb was chastised for his speculation on Oumuamua but has bounced back with backing for his Galileo Project - "the search for extraterrestrial technological signatures of Extraterrestrial Technological Civilizations (ETCs) from accidental or anecdotal observations".
Loeb published an interesting op ed in Scientific American yesterday outlining his opinions on AI-enabled self-replicating technologies exploring the galaxy and how we might be able to detect these extraterrestrial objects. It's a short read but demonstrates the core idea of his project.
Loeb is no lightweight here and has published a number of scientific papers (one example Lingam & Loeb 2019) working through the problems of alien panspermia, probabilities of encounters and implications of the galactic environments on extraterrestrial life.
