(16,926 posts)Although I'm highly doubtful of the success of SETI for precisely the reason I mentioned - there is likely an extremely narrow slice of time during which any civilization would rely on broadcast technology that would be detected. We are already on a sharp downward turn here with most communication taking place via fiber, coax cable and satellite (see: http://www.bidstrup.com/seti.htm).
The only time I read Kaku discussing energy depletion and climate change was to dismiss them as challenges that humanity would overcome, without really getting into the details. I haven't read or viewed all of his works, admitted.
I'm not sure what you mean by "recall radio waves and the two Voyagers". Was that something you felt I'd suggested should or could happen?
