Sean Carrol has a great podcast interview with Avi Loeb. https://www.preposterousuniverse.com/podcast/2021/01/25/131-avi-loeb-on-taking-aliens-seriously/ https://www.preposterousuniverse.com/podcast/2021/01/25/131-... The recent UFO hype (in the atmosphere) is annoying, but Avi Loeb is not one of those guys. I think Loeb is correct in his opinion that astrophysicists have a prejudice against looking for techno-signatures. This might lead to missing some technosignatures if they exist. Paying some attention towards anomalies might be a discovery. Avi Loeb points out that after Pan-STARRS survey increased the number of observations, the first interstellar object in the solar system was discovered very soon afterwards. It's very unlikely that weird object Oumuamua just happened to be there on that time. Other objects like Oumuamua are probably detected soon (within a decade or so) and what it really is can be cleared out. It will not stay as a mystery forever.
