David is one of the world’s best-known philosophers of mind and thought leaders on consciousness. I was a freshman at the University of Toronto when I first read some of his work. Since then, Chalmers has been one of the few philosophers (together with Nick Bostrom) who has written and spoken publicly about the Matrix simulation argument and the technological singularity. (See, for example, David’s presentation at the 2009 Singularity Summit or read his The Singularity: A Philosophical Analysis)

During our conversation with David, we discuss topics such as: how and why Chalmers got interested in philosophy; and his search to answer what he considers to be some of the biggest questions – issues such as the nature of reality, consciousness, and artificial intelligence; the fact that academia in general and philosophy, in particular, doesn’t seem to engage technology; our chances of surviving the technological singularity; the importance of Watson, the Turing Test and other benchmarks on the way to the singularity; consciousness, recursive self-improvement, and artificial intelligence; the ever-shrinking of the domain of solely human expertise; mind uploading and what he calls the hard problem of consciousness; the usefulness of philosophy and ethics; religion, immortality, and life-extension; reverse engineering long-dead people such as Ray Kurzweil’s father.

Most of our progress in disease treatment and prevention to date has been the product of the linear process of hit-or-miss efforts to find useful interventions. Because we have lacked tools for systematically exploring all possible treatments, discoveries under this paradigm have owed a lot to chance. Likely the most notable chance breakthrough in medicine was the accidental discovery of penicillin — which opened up the antibiotic revolution and has since saved perhaps as many as 200 million lives. But even when discoveries aren’t literally accidental, it still takes good fortune for researchers to achieve breakthroughs with traditional methods. Without the ability to exhaustively simulate possible drug molecules, researchers have to rely on high-throughput screening and other painstaking laboratory methods, which are much slower and more inefficient.

To be fair, this approach has brought great benefits. A thousand years ago, European life expectancy at birth was just in the twenties, since so many people died in infancy or youth from diseases like cholera and dysentery, which are now easily preventable. By the middle of the nineteenth century, life expectancy in the United Kingdom and the United States had increased to the forties. As of 2023, it has risen to over eighty in much of the developed world. So, we have nearly tripled life expectancy in the past thousand years and doubled it in the past two centuries. This was largely achieved by developing ways to avoid or kill external pathogens — bacteria and viruses that bring disease from outside our bodies.

Today, though, most of this low-hanging fruit has been picked. The remaining sources of disease and disability spring mostly from deep within our own bodies. As cells malfunction and tissues break down, we get conditions like cancer, atherosclerosis, diabetes, and Alzheimer’s. To an extent we can reduce these risks through lifestyle, diet, and supplementation — what I call the first bridge to radical life extension. But those can only delay the inevitable. This is why life expectancy gains in developed countries have slowed since roughly the middle of the twentieth century. For example, from 1,880 to 1900, life expectancy at birth in the United States increased from about thirty-nine to forty-nine, but from 1980 to 2000 — after the focus of medicine had shifted from infectious disease to chronic and degenerative disease — it only increased from seventy-four to seventy-six.

The American computer scientist and techno-optimist Ray Kurzweil is a long-serving authority on artificial intelligence (AI). His bestselling 2005 book, The Singularity Is Near, sparked imaginations with sci-fi like predictions that computers would reach human-level intelligence by 2029 and that we would merge with computers and become superhuman around 2045, which he called “the Singularity”. Now, nearly 20 years on, Kurzweil, 76, has a sequel, The Singularity Is Nearer – and some of his predictions no longer seem so wacky. Kurzweil’s day job is principal researcher and AI visionary at Google. He spoke to the Observer in his personal capacity as an author, inventor and futurist.

Why write this book? The Singularity Is Near talked about the future, but 20 years ago, when people didn’t know what AI was. It was clear to me what would happen, but it wasn’t clear to everybody. Now AI is dominating the conversation. It is time to take a look again both at the progress we’ve made – large language models (LLMs) are quite delightful to use – and the coming breakthroughs.

THE SINGULARITY IS NEARER: When We Merge With A.I., by Ray Kurzweil ______ A central conviction held by artificial intelligence boosters, but largely ignored in public discussions of the technology, is that the ultimate fulfillment of the A.I. revolution will require the deployment of microscopic robots into our veins. In the short term, A.I. may help us print clothing on demand, help prevent cancer and liberate half of the work force. But to…

Technological singularity: a hypothetical event where artificial intelligence (AI) surpasses human capabilities and leads to a transformative cascade of change.

Technological singularity: a hypothetical event where artificial intelligence (AI), pushed by exponential growth in computational power and intelligence, surpasses human capabilities and leads to a transformative cascade of change.

Coined by mathematician John von Neumann and popularized by futurist Ray Kurzweil, the singularity signifies a critical moment in human history—one where the trajectory of civilization takes an unpredictable turn and the boundaries between humans and machines blur. Kurzweil argued that technological progress follows an exponential trajectory and predicted that the singularity would occur around the year 2045, leading to a merging of human and machine intelligence and unprecedented levels of innovation.

For over five decades, futurist Raymond Kurzweil has shown a propensity for understanding how computers can change our world. Now he’s ready to anoint nanorobots as the key to allowing humans to transcend life’s ~120-year threshold.

As he wrote—both in the upcoming The Singularity is Nearer book (set for release on June 25) and in an essay published in Wired —the merging of biotechnology with artificial intelligence will lead to nanotechnology helping “overcome the limitations of our biological organs altogether.”

As our bodies accumulate errors when cells reproduce over and over, it invites damage. That damage can get repaired quickly by young bodies, but less so when age piles up.
