One
who advocates the idea that technological progress will cause a singularity in human history. (cf. Singularity in Extropy
#7.) [Mark Plus, August 1991]
Originally
defined by Mark Plus to mean "one who believes the concept of a Singularity", this term has since been
redefined to mean "Singularity
activist" or "friend
of the Singularity";
that is, one who acts so as to bring about a Singularity.
