The technological singularity is the idea that the time people will take to make breakthroughs in different areas is getting shorter, and that one day, it will become so short that no-one knows what will happen. Predictions of the technological singularity come from people doing maths equations using different dates and using data to predict ahead or extrapolate.
The futurist 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 2025, computers will be as intelligent as human beings (see artificial intelligence). The major event of the singularity, Kurzweil asserts, will be that the vast majority of the human race will be uploaded into a worldwide supercomputer to live inside it in virtual reality, thus achieving immortality. 
Nobody really knows what the technological singularity will do other than the uploading of the human race into the supercomputer, or if it will even happen.
