Because it has not happened yet, nobody really knows what the technological singularity will do, or if it will even happen. Nonetheless, the technological singularity has been a subject in many science fiction works, such as "The Terminator", "The Matrix", and the Borg in "Star Trek". In most depictions of the singularity, machines have consciousness and humans are considered to be useless. The futurist (who studies about the future) and inventor Ray Kurzweil believes the "Singularity" will happen about the year 2045. The major impetus driving toward the singularity, according to Kurzweil, is that according to Moore's Law, computers are doubling in memory capacity every 18 months. According to Kurzweil, by 2029, computers will be as intelligent as human beings (see artificial intelligence).
