Since our current technologies advance exponentially on a timescale of several years, our future habitat on Earth will look entirely different a million years from now. What does a mature technological civilization look like after such a long time? Can it survive the destructive forces that its technologies unleash? One way to find out is to search for technosignatures of alien civilizations, dead or alive. Inevitably, all forms of life eventually disappear. The universe cools as it expands, and all stars will die 10 trillion years from now. In the distant future, everything will freeze; there will be no energy left to support life.
Perhaps, instead, captured CO2 could be injected into porous rock, such as subsurface basalt, similar to a technique pioneered by Carbfix in Iceland. Over a process of several years, carbon dioxide would solidify into calcite crystals and this bedrock could be quarried for use as a building material. As in ancient Egypt, monolithic slabs of stone could form pyramids, either built in situ to help bolster tourism in Iceland, the African Rift Valley, and other areas rich in malfic rock; or conveyed over unfathomably long distances for reasons that might seem obscure to future generations. Such structures would be durable and their construction would likely employ large masses of people, but the process would be extremely energy-intensive. Moreover, the majority of these pyramids’ volume would be taken up by the host rock, not sequestered carbon, meaning that we would need to construct far more than our original 138,462 pyramids.
Worldscraping has incredible potential. We’ll be able to extract our own data without needing Amazon or Google’s permission. We can make a better food database, a better catalogue of plants and wildlife, a better map of the world, anything you can imagine that requires information about the real world, all with far less work and in far less time.
The big losers from worldscraping will be incumbent companies and tech giants. They’ll want to keep worldscraping for themselves, and they’ll say it’s because only they can be trusted to use it.
But they aren’t the only ones who can keep us safe. There are ways to secure computing devices without unaccountable gatekeepers or expert users. Contrary to what Apple would have you believe, we all use software every day that’s as safe as anything inside their walled garden, if not safer. We need to support and learn from those third-party companies and open source communities as we head into the next generation of computing devices.
Should the Olympics cease to exist? It’s a question I never thought I’d ask. I did gymnastics when I was younger and have been thoroughly obsessed with the sport ever since. I even built my writing career around gymnastics, so the Olympics — where the sport is a perennial favorite — factor heavily into my work (and my income).
“I had an emotional attachment to the Olympics growing up as an athlete,” Itani said. “It’s such a well-produced media spectacle. It’s amazing to see these athletes, the quality of the camera, the angles, the stories of the athletes in the Olympics that are covered by the media.”
I experienced the same emotional attachment that Itani described — and still do. I was aware of all of the harm that the Olympics brought to communities but I took a reformist approach: we could preserve the good and eliminate the bad through smart policies and transparency. But reform hasn’t worked. In 2014, the IOC introduced Agenda 2020 to make reforms to the bidding process and curb the excesses of hosting the Games. Yet the tab for Tokyo 2020 is more than triple what was originally projected.
Game theory shows us that, regardless of what an individual believes, it is in their own self-interest to wear a mask.
While the conflict surrounding wearing masks will persist, these insights shed light on a new perspective on the benefits of wearing masks during this time, even outside the realm of public health and science. Next time you encounter a family member, friend, co-worker, or even a stranger who is against wearing masks, consider explaining that their decision, although self-interested in the short-run, only hurts them in the long run.
Just like in the prisoner’s dilemma, cooperation results in the most efficient outcome. If we cooperate and wear masks, the pandemic will be better mitigated and we may finally find true freedom again.
Salmon are at home in color. Whipping her tail, a female salmon spends two days making a depression in the riverbed called a redd—the word probably comes from the Early Scots ridden, meaning “to clear”—into which she deposits her roe. Fertilized, these red spheres of nutrients encase young salmon, who eat their way out, taking the color inside. Once the eggs are depleted, salmon swim to the ocean in search of food. There, they feed on red-pink crustaceans, mostly shrimp and krill, as well as small fish with even smaller crustaceans in their digestive systems. From these, they absorb yellow-red orange fat-soluble pigments, called carotenoids, that tint salmon salmon.
