We Need a Far Better Plan for Dealing With Existential Threat

Posted by in categories: biotech/medical, existential risks, food, government, lifeboat, military, robotics/AI

Here’s my latest Opinion piece just out for Newsweek. Check it out! Lifeboat Foundation mentioned.


We need to remember that universal distress we all had when the world started to shut down in March 2020: when not enough ventilators and hospital beds could be found; when food shelves and supplies were scarce; when no COVID-19 vaccines existed. We need to remember because COVID is just one of many different existential risks that can appear out of nowhere, and halt our lives as we know it.

Naturally, I’m glad that the world has carried on with its head high after the pandemic, but I’m also worried that more people didn’t take to heart a longer-term philosophical view that human and earthly life is highly tentative. The best, most practical way to protect ourselves from more existential risks is to try to protect ourselves ahead of time.

NASA Reveals How It Would Warn World of Impending Asteroid Disaster

Posted by in categories: asteroid/comet impacts, existential risks, military

When the Chicxulub impactor, a six-mile-wide asteroid, struck Earth 66 million years ago, the dinosaurs had no warning.

If an asteroid that size hit Earth today, a shock wave two million times more powerful than a hydrogen bomb would flatten forests and trigger tsunamis. A seismic pulse equal to a magnitude 10 earthquake would crumble cities.

And long after the impact, a cloud of hot dust, ash, and steam would blot out the sun, plunging the Earth into freezing cold.

Oppenheimer’s Grandson Signs Letter Saying AI Threatens “Life on Earth”

Posted by in categories: existential risks, military, robotics/AI

J. Robert Oppenheimer’s grandson is among the star-studded signatories of a new open letter about the dangers artificial intelligence poses to the planet.

The letter, which was issued by the Nelson Mandela-founded group The Elders in conjunction with the Future of Life Institute, calls on global decisionmakers to “show long-view leadership on existential threats,” including “ungoverned AI” and nuclear weapons.

Charles Oppenheimer, who founded the Oppenheimer Project to continue his grandfather’s mission of tempering scientific progress with “international cooperation and unity,” was joined by hundreds of others, including British billionaire Richard Branson, AI pioneer Geoffrey Hinton, writer and Carl Sagan widow Ann Druyan, and musician Peter Gabriel. In it, they warn that the world “is in grave danger” as we face down the perils of AI.

Asteroid Impact Near Berlin Reveals Rare Aubrite Treasures

Posted by in categories: asteroid/comet impacts, chemistry, existential risks

Jenniskens’ collaborators at the Museum für Naturkunde officially announced that the first examinations of one of these pieces with an electron beam microprobe prove the typical mineralogy and chemical composition of an achondrite of the aubrite type.

The official classification now aligns with what many suspected from merely looking at the images of the strange meteorites that fell near Berlin on January 21, 2024. They belong to a rare group called “aubrites.”

“They were devilishly difficult to find because, from a distance, they look like other rocks on Earth,” said SETI Institute meteor astronomer Dr. Peter Jenniskens. “Close up, not so much.”
