The Singularity is Far: A Neuroscientist’s View – Boing Boing:

But while I see an exponential trajectory in the amount of neurobiological data collected to date, the ploddingly linear increase in our understanding of neural function means that an idea like mind-uploading to machines being usefully deployed by the 2020s or even the 2030s seems overly optimistic.

Apparently Kurzweil is wrong and we won’t be getting virtual reality inducing, medical diagnoses capable nanobots for our brains in the coming decade. Shucks.
