It isn't. I first heard of the Singularity by reading Wikipedia's list of pseudosciences or something similar. I had decided to read it because there was a chance that something was miscategorized and I reasoned that if there was an idea that people thought was pseudoscientific but was actually correct, it could be important to know that. The Wikipedia article was filled with quotes from Kurzweil and pictures of exponential graphs, so I dismissed the Singularity group of memes, while still believing that AI was achievable and that it would have a profound effect on the world.
