"I'm telling my story because I see a pressing need to prepare thinking adults for the outcome of the present search activity - the imminent detection of signals from an extra terrestrial civilization. This detection, which I fully expect to witness before the year 2000, will profoundly change the world."
Frank Drake, 1993.
I remembered this from the hilariously hopeful book: Is Anyone out there? which had me rocking in the aisles 21 years ago!
