Senior Astronomer at the SETI Institute Seth Shostak joined us by Zoom from California to discuss the failure so far to detect extra-terrestrial intelligence by searching the sky for artificial radio signals, and new initiatives being developed or under consideration. We are likely to encounter alien robots before alien biology, he thinks. Seth spends much energy on outreach activities, publishing numerous popular articles on science, giving talks to lay audiences, and hosting the SETI Institute’s weekly science radio show, “Big Picture Science.”
