resulting in unforeseeable changes to human civilization. According to the most popular version of the singularity hypothesis, called intelligence explosion, 
an upgradable intelligent agent will eventually enter a "runaway reaction" of self-improvement cycles, each new and more intelligent 
generation appearing more and more rapidly, causing an "explosion" in intelligence and resulting in a powerful superintelligence that qualitatively 
far surpasses all human intelligence.
