Happy Birthday SETI

The March 29 Are We Alone program titled SETI: Now What? celebrates 50 years of the search for extraterrestrial intelligence. Included are interviews with current and former participants, a description of the famous Drake Equation (by Drake), and, of course, memories of Carl Sagan. It’s a great podcast.
I’m optimistic. I’m beginning to think that second-nature use of collaborative technologies by non-technologists, both for social engagement as well as for work, could reach a tipping point much sooner than I had thought. It’s not going to be completely smooth sailing, though.
