Longevity is not the meaning of life

So you want to live forever? Excellent. You’ve come to the right place. Here at Gilgamesh-Makropulos Limited, we know a thing or two about immortality. First, we need to track your metrics: biological age versus chronological age, average number of erections per night, metabolic health, maximal oxygen consumption, heart rate variability, stool volume and colour and salivary flow rate. Sound good? My assistant will fetch the paperwork.  This might seem like the beginning of a potboiler sci-fi rip-off. But it’s actually closer to our reality than Bernard Williams would have liked. While we still haven’t achieved immortality, the cult of ‘longevity’ has become something of a gold rush in recent years.

The art of aging

More than 30 contemporary artists have contributed to the Wellcome Collection’s latest exhibition, which asks what it’s like to age at a time of unparalleled longevity. But as so often happens at the Wellcome’s exhibitions, it’s the ephemera that draw the eye first. “These 2 men are the same age,” says a leaflet advertising Kellogg’s All-Bran breakfast cereal. “One has driving power – energy – the will to succeed. The other is listless – tired all the time – it is an effort for him to plod through each day’s work.” The point being that aging is, to a not inconsiderable degree, something we do to ourselves, and something we do to each other. It is a process, not an event.

An AI visionary looks forward to the best of all possible worlds

In 1993 Vernor Vinge popularised the notion of the Singularity – the point at which exponentially accelerating trends in multiple technologies move out of control in an endless positive feedback loop. Vinge was a science fiction writer; Ray Kurzweil is not. In 1993 he had already pioneered optical character recognition and synthesisers that could precisely mimic real instruments. His mission crystallised into making Vinge’s conceit a reality. He is principal researcher and ‘AI visionary’ at Google – and principal proselytiser, too, through any number of portentously titled books. The Age of Spiritual Machines (1999) set out his stall; The Singularity is Near (2005) staked a claim for human-level intelligence in computers by 2029 and a generalised apotheosis in 2045.

The case for cold weather

From our US edition

Pennsylvania experienced a heat wave last week, with temperatures soaring into the mid-80s. It was not to last. This morning it was a balmy 33°F, with that bone-chilling dampness and threat of snow showers that can only mean one thing: spring! When friends and family who live in warm places send me photos of the beach and brag about taking long walks in the sunshine, I block out their bragging with a defiant flip of my hood and insist that people who live in cold places are tougher. We have more character. True grit. And it turns out that may actually be true. "Cold temperature extends longevity and prevents disease-related protein aggregation," according to a new peer-reviewed study from Germany's University of Cologne. Longevity, i.e.
