I find the Fermi paradox quite shallow too, but for different reasons. Even if a twin sister civilization of humankind existed somewhere on a different planet revolving around a different star, how would we detect it? Space is huge, and hoping to detect some signs of intelligence close to a distant star is like trying to photograph a firefly that flies around a lighthouse, from miles away in the sea, only about 1 trillion times more challenging. You just need to see what faint a signal we receive form the Voyagers, which are deliberately pointing their antennas at us and are thousands of times closer to us than any star to appreciate how improbable it would be for us to ever detect extraterrestrial communication.
