This thread is not so much about the question whether “humanity will be spread out among vastly more star systems in the universe” (Meno), but mainly about the question whether all (all!) humans will be replaced by machines and how this will happen. Keywords: machines in the conventional sense, machines in the sense of artificial intelligence (AI), cyborgs, androids.
It is more topical than ever, even more topical than in 2014 (April 3), when Arminius opened this thread.
