Ray Kurzweil, Director of Engineering at Google, on the year humans will stop aging faster than science can reverse it: He is one of the most prominent futurists in tech, and he believes that year is closer than most people think. He explains the core concept: "By around 2032, people who are diligent with their health are going to reach what we call longevity escape velocity. This is when scientific breakthroughs will add more time to our remaining life expectancy than is going by." In other words, for every year that passes, science could be adding more than a year back to your life expectancy. "So we could be going backwards in time as far as our health is concerned." Kurzweil sees this transformation as part of a larger shift in what it means to be human: "As we emerge with AI in this way, we will become a hybrid species. We will still be human but will be enhanced by AI." The mechanism that makes this possible? AI's ability to process biological complexity at a scale humans never could: "We'll soon have the ability to rapidly test billions of possible molecular sequences to find cures ultimately for all diseases." For Kurzweil, this isn't about chasing immortality for its own sake. He frames overcoming biological limits as a continuation of something humanity has always done: "Overcoming the limitations of biology is not a new story." His personal motivation is refreshingly simple: "It's for why I want to live indefinitely because I want to see my loved ones and I want to continue working on my creative projects. I don't see a time when I would not feel that way."
