Living ‘forever’ would cause extreme risk aversion

Posted by in categories: life extension, transportation

An article discussing why extreme risk aversion deriving from indefinite lifespans is neither very likely, nor rational.


There’s a theory suggesting that, if we could live indefinitely, we might become extremely risk-averse. Presently, regardless of when you die, you ‘only’ lose a handful of decades of life at worst, because you would have died of old age eventually anyway. However, the reasoning goes, if you could live for an indefinitely long time, your untimely death would cost you no less than eternity; the conclusion is that, in order to avoid such an unimaginable loss, people wouldn’t dare taking even the most insignificant risks, such as crossing the street, ultimately making their own lives quite miserable.

The problem with this argument is that it hinges on a flawed assumption. The assumption is that we dare taking any risks at all only because we know that in a few decades at best we’re going to be dead anyway. Why do you take a plane for a holiday at the Antipodes? Because you’re going to die anyway when you’re old. Why do you go on a rollercoaster ride? Because the reaper would get you sooner or later anyway. Why do you go out without an umbrella even though it looks like it might rain? Because pneumonia would cut your life only a few decades shorter. Note that this argument also answers the age-old question, ‘Why did the chicken cross the street?’ Because YOLO.

This is not how smart people (or chickens) think. The question is one of magnitude of benefits and risks of a certain course of action. Consider the case of John, 40 years old, taking a plane from New York to Madrid for a two-week holiday. There is a chance the plane might fall into the Atlantic Ocean during the flight, in which case John would die. The chance isn’t very big, but it’s not zero nonetheless. If the plane doesn’t fall, then John gets his holiday (the benefits); however, if the plane falls, not only does John not get his holiday, but he also loses his life. At age 40, John isn’t exactly a youngster any more, but he does have some 40 years of life left, though. While the perceived value of the holiday and the remaining 40 years of life are subjective, it is quite reasonable to say that two weeks in Madrid aren’t worth losing 40 years of life.

Top 100 Most Disruptive Space Companies in 2017

For decades, space exploration and experimentation has been the playground for world governments and wealthy academics. Exposure to space was limited to sci-fi, the odd government broadcast, and conspiracy theories. Normal people could only buy their loved ones stars or plots of cosmic land as a sentimental gift.

Researchers build first deployable, walking, soft robot

Posted by in categories: robotics/AI, space

(Phys.org)—Researchers have built the first robot made of soft, deployable materials that is capable of moving itself without the use of motors or any additional mechanical components. The robot “walks” when an electric current is applied to shape-memory alloy wires embedded in its frame: the current heats the wires, causing the robot’s flexible segments to contract and bend. Sequentially controlling the current to various segments in different ways results in different walking gaits.

The researchers expect that the ’s ability to be easily deployed, along with its low mass, low cost, load-bearing ability, compact size, and ability to be reconfigured into different forms may make it useful for applications such as space missions, seabed exploration, and household objects.

The scientists, Wei Wang et al., at Seoul National University and Sungkyunkwan University, have published a paper on the new robot and other types of deployable structures that can be built using the same method in a recent issue of Materials Horizons.

Los Angeles mayor sounds open to Elon Musk’s tunneling plan

Posted by in categories: Elon Musk, transportation

Elon Musk’s concept of solving traffic congestion by digging networks of tunnels may have a fan in Los Angeles Mayor Eric Garcetti.

Speaking about the city’s transit issues Sunday morning on ABC 7‘s “Eyewitness Newsmakers,” Garcetti mentioned the possibility of tunneling: “Like many other cities have, I’d love to see maybe even with the new tunneling technology that people like Elon Musk is looking at, whether we could have a quick and direct route from LAX to Union Station.”
