In the year 2050, if Ray Kurzweil is right, nanoscopic robots will be zooming throughout our capillaries, transforming us into nonbiological humans. We will be able to absorb and retain the entirety of the universe’s knowledge, eat as much as we want without gaining weight, shape-shift into just about any physical form imaginable, live free from disease, and die at the time of our choosing. All of this will be thrust on us by something that Kurzweil calls the Singularity, a theorized point in time in the not-so-distant future when machines become vastly superior to humans in every way, aka the emergence of true artificial intelligence.
Watch Ray Kurzweil talk about the Singularity on Motherboard.
