Check out this talk from the inventor of the K-NFB reader. Beyond his innovations in adaptive products for the visually impaired, Kurzweil is a leading thinker on radical human potential.
According to his Wikipedia page, Kurzweil “has been a pioneer in the fields of optical character recognition (OCR), text-to-speech synthesis, speech recognition technology, and electronic keyboard instruments. He is the author of several books on health, artificial intelligence (AI), transhumanism, the technological singularity, and futurism”. A movie based on his techno-philosophies will be released this year..
