I have to mention an article by Allen which I think is the single best critique of the idea fo the "singularity" which I have seen. Paul Allen: The Singularity Isn't Near https://www.technologyreview.com/s/425733/paul-allen-the-sin...
Kurzweil makes this comment:
IBM is now working with Nuance (a company I originally founded as Kurzweil Computer Products) to have Watson read tens of thousands of medical articles to create a medical diagnostician.

Given the history of Watson since these articles were written, I think it lends more weight to Allen's side of the argument.
