With all due respect to Kurzweil his predictions fall within the window of him being alive to see it. He keeps pushing the dates further and further away yet close enough that he could conceivably be alive at that date. Going by Gibson's old maxim "the future is here, but it is not widely distributed" I wonder what promising tech we have today that could be widely distributed by 2030. 3D printers - cheaper than 10 years ago but still quite limited in capabilities DNS sequencers - cheaper than 10 years ago but still limited About the only thing promising is Alpha Zero which is only a small part of the puzzle. We still need some massive new tech/science developments to achieve Kurzweil's vision. Distributing/improving existing tech will not cut it.
