Futurist Ray Kurzweil Pulls Out All the Stops (and Pills) to ...

Futurist Ray Kurzweil

Kurzweil does not believe in half measures. He takes 180 to 210 vitamin and mineral supplements a day, so many that he doesn't have time to organize them all himself. So he's hired a pill wrangler, who takes them out of their bottles and sorts them into daily doses, which he carries everywhere in plastic bags. Kurzweil also spends one day a week at a medical clinic, receiving intravenous longevity treatments. The reason for his focus on optimal health should be obvious: If the singularity is going to render humans immortal by the middle of this century, it would be a shame to die in the interim. To perish of a heart attack just before the singularity occurred would not only be sad for all the ordinary reasons, it would also be tragically bad luck, like being the last soldier shot down on the Western Front moments before the armistice was proclaimed.

Exponential growth is unintuitive, because it can be imperceptible for a long time and then move shockingly fast. It takes training and experience, and perhaps a certain analytical coolness, to trust in exponential curves whose effects cannot be easily perceived.

According to Grossman and other singularitarians, immortality will arrive in stages. First, lifestyle and aggressive antiaging therapies will allow more people to approach the 125-year limit of the natural human lifespan. This is bridge one. Meanwhile, advanced medical technology will begin to fix some of the underlying biological causes of aging, allowing this natural limit to be surpassed. This is bridge two. Finally, computers become so powerful that they can model human consciousness. This will permit us to download our personalities into nonbiological substrates. When we cross this third bridge, we become information. And then, as long as we maintain multiple copies of ourselves to protect against a system crash, we won't die.

Kurzweil himself started across the first bridge in 1988. That year, he confronted the risk that had been haunting him and began to treat his body as a machine. He read up on the latest nutritional research, adopted the Pritikin diet, cut his fat intake to 10 percent of his calories, lost 40 pounds, and cured both his high cholesterol and his incipient diabetes. Kurzweil wrote a book about his experience, The 10% Solution for a Healthy Life. But this was only the beginning.

Kurzweil met Grossman at a Foresight Nanotech Institute meeting in 1999, and they became research partners. Their object of investigation was Kurzweil's body. Having cured himself of his most pressing health problems, Kurzweil was interested in adopting the most advanced medical and nutritional technologies, but it wasn't easy to find a doctor willing to tolerate his persistent questions. Grossman was building a new type of practice, focused not on illness but on the pursuit of optimal health and extreme longevity. The two men exchanged thousands of emails, sharing speculations about which cutting-edge discoveries could be safely tried.

Though both Grossman and Kurzweil respect science, their approach is necessarily improvisational. If a therapy has some scientific promise and little risk, they'll try it. Kurzweil gets phosphatidylcholine intravenously, on the theory that this will rejuvenate all his body's tissues. He takes DHEA and testosterone. Both men use special filters to produce alkaline water, which they drink between meals in the hope that negatively charged ions in the water will scavenge free radicals and produce a variety of health benefits. This kind of thing may seem like quackery, especially when promoted by various New Age outfits touting the "pH miracle of living." Kurzweil and Grossman justify it not so much with scientific citations — though they have a few — but with a tinkerer's shrug. "Life is not a randomized, double-blind, placebo-controlled study," Grossman explains. "We don't have that luxury. We are operating with incomplete information. The best we can do is experiment with ourselves."

Kurzweil predicts that by the early 2030s, most of our fallible internal organs will have been replaced by tiny robots. We'll have "eliminated the heart, lungs, red and white blood cells, platelets, pancreas, thyroid and all the hormone-producing organs, kidneys, bladder, liver, lower esophagus, stomach, small intestines, large intestines, and bowel. What we have left at this point is the skeleton, skin, sex organs, sensory organs, mouth and upper esophagus, and brain."

Kurzweil has no plan for retirement. He intends to sustain himself indefinitely through his intelligence, which he hopes will only grow. A few years ago he deployed an automated system for making money on the stock market, called FatKat,

And these are the merely intellectual protests Kurzweil receives. The fundamental cause for loneliness, if you are a prophet of the singularity, is probably more profound. It stems from the simple fact that the idea is so strange. "Death has been a ubiquitous, ever-present facet of human society," says Kurzweil's friend Martine Rothblatt, founder of Sirius radio and chair of United Therapeutics, a biotech firm on whose board Kurzweil sits. "To tell people you are going to defeat death is like telling people you are going to travel back in time. It has never been done. I would be surprised if people had a positive reaction."

"If you took a poll of primitive man, happiness would be getting a fire to light more easily," he says. "But we've expanded our horizon, and that kind of happiness is now the wrong thing to focus on. Extending our knowledge and casting a wider net of consciousness is the purpose of life."

One day, sitting in his office overlooking the suburban parking lot, I ask Kurzweil if being a singularitarian makes him happy. "If you took a poll of primitive man, happiness would be getting a fire to light more easily," he says. "But we've expanded our horizon, and that kind of happiness is now the wrong thing to focus on. Extending our knowledge and casting a wider net of consciousness is the purpose of life." Kurzweil expects that the world will soon be entirely saturated by thought. Even the stones may compute, he says, within 200 years.
