If we survive it, the singularity will probably be given a date in hindsight. However, i doubt that living though it will be an overnight change. I think some people are mistakenly including sentient AI as a requirement for the singularity. In such a scenario sentience could suddenly appear and infect advance systems round the world overnight.

I don't see why the singularity couldn't occur over a period of time without computers becoming sentient and then one day it seems to be everywhere. Gradually, then suddenly as Hemingway put it. The main requirement for the singularity is that the future becomes unpredictable.

I would argue that what we are seeing happening now in the AI sector qualifies as a symptom of the singularity having started. At this point it might be wiser to start thinking about ensuring a soft landing for yourself for whenever the carnage arrives at your occupation in the next X years.
