“”It's as if you took a lot of very good food and some dog excrement and blended it all up so that you can't possibly figure out what's good or bad. It's an intimate mixture of rubbish and good ideas, and it's very hard to disentangle the two, because these are smart people; they're not stupid.
|—Douglas Hofstadter on Kurzweil|
Ray Kurzweil is a well-known futurist and advocate of the transhumanist belief cluster with a truly overwhelming fear of death. He makes predictions about what science and humanity will achieve in the next ten, twenty, or hundred years, and the press lap it up.
 The good stuff
Kurzweil is, in fact, a genius. He was a major pioneer in the fields of optical character recognition and computer-assisted reading (Stevie Wonder is a personal friend of his) as well as digital music synthesis (his K250 keyboard was the first to use recorded samples for tone generation).  From a technological standpoint, Kurzweil is nearly as important to modern music as Les Paul (inventor of the solid-body electric guitar), and he's also an important figure in handicap accessibility.
 Transferable expertise
Kurzweil has an unfortunate tendency to think that being brilliant at computer science means every other specialty can be treated as a special case of computer science. He thinks that the genome contains all the information needed to grow a brain, therefore it is a problem of Kolmogorov complexity[wp] and computer science, therefore we will be able to simulate one on computers by 2030. Experts on the evolution of brains think Kurzweil does not understand biology and thinks the genome works like a blueprint, whereas most qualified biologists think the right analogy is a recipe that takes as a starting assumption the informational content of the rest of life on Earth. In the case of the human brain, it literally cannot physically develop correctly except in the presence of a human culture. This leads to a certain exasperation on the part of those who actually know what they're talking about.
 Singularity University
Kurzweil is keen to share his knowledge and insight. You, yes you the corporate executive, can spend $15,000 of company money on a 9-day Executive Training Session, or a 10-week graduate studies course for $25,000, to learn all about exponentially advancing technologies.
In line with most misconceptions about nanotechnology, Kurzweil thinks nanobots of the "industrial robot scaled down a billion times" kind are achievable, rather than requiring violations of physics. He then actively propagates this misconception.
 Nutritional woo
He is very fond of nutritional supplements (he takes 200 vitamin pills a day) and alkaline water and getting scientifically untested longevity treatments. When his followers start an argument with "look, Kurzweil's a smart guy, right?" see if they will acknowledge his propensity for untested alt-med woo as being prima facie evidence that his undoubted intelligence in no way means he isn't capable of being utterly wrong.
He also sells nutritional supplements for longevity which are as good as any others, i.e. 0% solid verified science and 100% wishful thinking. So is he a charlatan or a fool?

Kurzweil may be technically, though not usefully, approximately correct about the genome containing almost all the information needed to grow a fresh newborn's brain.
