So says neuroscientist David Linden (Johns Hopkins University School of Medicine and Chief Editor of the Journal of Neuropysiology) in this essay.
Basic gist: All of that cool stuff that Ray Kurzweil told you about, like the nanobots swimming around in your brain and uploading yourself into a computer? Um, it ain’t gonna happen.
I am a neurobiologist and I have spent the past 28 years engaged in studies of the cellular and molecular basis of memory and cognition. I am an optimist and a technophile, but I believe that I speak for the vast majority of brain researchers when I express serious doubts about Kurzweil’s timetable.
