re: SETI has a foolish perspective
They could all be like us, sitting around listening and not sending. At what point in our development do we seriously try to send continuous, or at least regular messages. All we've done is a couple of sporadic cryptic messages in the last 50 years. It would have to be an amazing stroke of luck for even an advanced civilization to catch one of them. Of course you have to have someone willing to spend the $$$$$$$ to set up a regular broadcast to ET.
