I discussed some of Ray Kurzweil's intriguing ideas in this post.
The New York Times recently discussed them as well:
Two decades ago he predicted that “early in the 21st century” blind people would be able to read anything anywhere using a handheld device. In 2002 he narrowed the arrival date to 2008. On Thursday night at the festival, he pulled out a new gadget the size of a cellphone, and when he pointed it at the brochure for the science festival, it had no trouble reading the text aloud.
This invention, Dr. Kurzweil said, was no harder to anticipate than some of the predictions he made in the late 1980s, like the explosive growth of the Internet in the 1990s and a computer chess champion by 1998. (He was off by a year — Deep Blue’s chess victory came in 1997.)
