Keep in mind that the term technological singularity as it was first coined merely means reaching the point where the advancement of technology happens so fast that your ability to predict future advancements diminishes to the point of not being able to predict with any accuracy at all.
It is a function of recognizing the exponential growth of technological advancement.
In the context of AI, I believe it specifically refers to the point when AI starts programming new, slightly better AIs and the exponential nature of that feedback loop
