===Future predictions===

In 1999, Kurzweil published a second book, ''[[The Age of Spiritual Machines]]'', which explains his futurist ideas in more depth. In it, he says that with radical life extension will come radical life enhancement. He says he is confident that within 10 years{{When|reason=10 years from 1999 (2009) or 10 years since the redaction of the article?|date=February 2025}} we will have the option to spend some of our time in 3D virtual environments that appear just as real as reality, but that they will not yet be able to directly interact with our nervous system. He expounds on his prediction about [[nanorobotics]], claiming that within 20 years millions of blood-cell sized devices, called nanobots, will fight disease inside our bodies and improve our memory and cognitive abilities. Kurzweil also believes a machine will pass the [[Turing test]] by 2029. He says that humans will be a hybrid of biological and non-biological intelligence that becomes increasingly dominated by its non-biological component.<ref>{{Cite web |last=Eugenios |first=Jillian |date=June 3, 2015 |title=Ray Kurzweil: Humans will be hybrids by 2030 |url=https://money.cnn.com/2015/06/03/technology/ray-kurzweil-predictions/index.html |access-date=2022-09-01 |website=CNNMoney}}</ref> In ''[[Transcendent Man]]'', he writes, "We humans are going to start linking with each other and become a metaconnection; we will all be connected and omnipresent, plugged into a global network that is connected to billions of people and filled with data."<ref name="transcendentman.com" />

In 2008, Kurzweil said in an expert panel in the [[National Academy of Engineering]] that [[solar power]] will scale up to produce all of humanity's energy needs in 20 years. According to him, we need to capture only 1 part in 10,000 of the energy from the Sun that hits Earth's surface to meet all of humanity's energy needs.<ref>{{cite web |url=http://www.livescience.com/environment/080219-kurzweil-solar.html |title=Solar Power to Rule in 20 Years, Futurists Say |publisher=LiveScience |date=February 19, 2008 |access-date=2011-03-27}}</ref>
