  The technological singularity refers to a hypothetical scenario in which
technological advances virtually explode. The most popular scenario is the
creation of super-intelligent algorithms that recursively create ever higher
intelligences. It took many decades for these ideas to spread from science
fiction to popular science magazines and finally to attract the attention of
serious philosophers. David Chalmers' (JCS 2010) article is the first
comprehensive philosophical analysis of the singularity in a respected
philosophy journal. The motivation of my article is to augment Chalmers' and to
discuss some issues not addressed by him, in particular what it could mean for
intelligence to explode. In this course, I will (have to) provide a more
careful treatment of what intelligence actually is, separate speed from
intelligence explosion, compare what super-intelligent participants and
classical human observers might experience and do, discuss immediate
implications for the diversity and value of life, consider possible bounds on
intelligence, and contemplate intelligences right at the singularity.
