Life and Intelligent life
I didn't listen to the broadcast but I have heard this debate a number of times. Extraterrestrial life, of course we should look for it. And we don't have to look far. Mars, Jupiter and Saturn's moons. The clouds above Venus. Extraterrestrial intelligence is trickier, because of the implications, but I would argue that we are already doing that indirectly by broadcasting our entire civilization out to the universe, so yes we should search for intelligence as well.
