power will scale up to produce all the energy needs of Earth's people in 20 years. According to Kurzweil, we only need to capture 1 part in 10,000 of the energy from the Sun that hits Earth's surface to meet all of humanity's energy needs. Stance on nuclear weapons On a Lex Fridman interview on September 17, 2022, Kurzweil explained his worries about technology being used for violence. When asked about nuclear armaggedon and the Russo-Ukrainian War, Kurzweil stated: "I don't think (nuclear war) is going to happen despite the terrors of that war. It is a possibility but it's unlikely. Even with the tensions we've had with the nuclear power plant that's been taken over. It's very tense but I don't actually see a lot of people worrying that's going to happen. I think we'll avoid that. We had two nuclear bombs go off in (1945) so now we're 77 years later... we've never had another one go off through anger... there are other dangers besides nuclear weapons." Reception Praise Kurzweil was called "the ultimate thinking machine" by Forbes and a "restless genius" by The Wall Street Journal. PBS included Kurzweil as one of 16 "revolutionaries who made America" along with other inventors of the past two centuries. Inc. magazine ranked him Number 8 among the "most fascinating" entrepreneurs in the US and called him "Edison's rightful heir". Bill Gates called him "the best at predicting the future of artificial intelligence". Criticism Although technological singularity is a popular concept in science fiction, some authors such as Neal Stephenson and Bruce Sterling have voiced skepticism about its real-world plausibility. Sterling expressed his views on the singularity scenario in a talk at the Long Now Foundation entitled The Singularity: Your Future as a Black Hole. Other prominent AI thinkers and computer scientists such as Daniel Dennett, Rodney Brooks, David Gelernter and Paul Allen have also criticized Kurzweil's projections. In the cover article of the December 2010 issue of IEEE Spectrum, John Rennie criticizes Kurzweil for several predictions that failed to become manifest by the originally predicted date. "Therein lie the frustrations of Kurzweil's brand of tech punditry. On close examination, his clearest and most successful predictions often lack originality or profundity. And most of his predictions come with so many loopholes that they border on the unfalsifiable." Bill Joy, cofounder of Sun Microsystems, agrees with Kurzweil's timeline of future progress, but
