That statement, now signed by twice as many concerned citizens, warned about the risk of human extinction from AI, which was perhaps a bit of an overreach, because ⊠well, extinction? Come on! Thatâs just a movie with Arnold Schwarzenegger.
What they should have warned about was jobs â the redundancy and destitution of most of humanity, unless thereâs some kind of universal income funded by taxes on robots.
What no-one talks about, as the AI revolution unfolds in stock market hype and scientific gung-ho, is what theyâre all really trying to do.

Asteroid impact simulation reveals climate and ecological disruptions
A new climate modeling study published in the journal Science Advances by researchers from the IBS Center for Climate Physics (ICCP) at Pusan National University in South Korea presents a new scenario of how climate and life on our planet would change in response to a potential future strike of a medium-sized (~500 m) asteroid.
The solar system is full of objects with near-Earth orbits. Most of them do not pose any threat to Earth, but some of them have been identified as objects of interest with non-negligible collision probabilities. Among them is the asteroid Bennu with a diameter of about 500 m, whichâaccording to recent studiesâhas an estimated chance of 1 in 2700 of colliding with Earth in September 2182. This is similar to the probability of flipping a coin 11 times in a row with the same outcome.
To determine the potential impacts of an asteroid strike on our climate system and on terrestrial plants and plankton in the ocean, researchers from the ICCP set out to simulate an idealized collision scenario with a medium-sized asteroid using a state-of-the-art climate model.
Scientists Simulated Bennu Crashing to Earth in September 2182. Itâs Not Pretty
Simulations of a potential impact by a hill-sized space rock event next century have revealed the rough ride humanity would be in for, hinting at what itâd take for us to survive such a catastrophe.
Itâs been a long, long time since Earth has been smacked by a large asteroid, but that doesnât mean weâre in the clear. Space is teeming with rocks, and many of those are blithely zipping around on trajectories that could bring them into violent contact with our planet.
One of those is asteroid Bennu, the recent lucky target of an asteroid sample collection mission. In a mere 157 years â September of 2,182 CE, to be precise â it has a chance of colliding with Earth.
How to keep AI from killing us all
If left unchecked, powerful AI systems may pose an existential threat to the future of humanity, say UC Berkeley Professor Stuart Russell and postdoctoral scholar Michael Cohen.
Society is already grappling with myriad problems created by the rapid proliferation of AI, including disinformation, polarization and algorithmic bias. Meanwhile, tech companies are racing to build ever more powerful AI systems, while research into AI safety lags far behind.
Without giving powerful AI systems clearly defined objectives, or creating robust mechanisms to keep them in check, AI may one day evade human control. And if the objectives of these AIs are at odds with those of humans, say Russell and Cohen, it could spell the end of humanity.
âDigital doppelgangersâ are helping scientists tackle everyday problemsâand showing what makes us human
As rising seas lap at its shore, Tuvalu faces an existential threat. In an effort to preserve the tiny island nation in the middle of the Pacific Ocean, its government has been building a âdigital twinâ of the entire country.
Digital twins are exactly what they sound likeâa virtual double or replica of a physical, real-world entity. Scientists have been creating digital twins of everything from molecules, to infrastructure, and even entire planets.
Itâs also now possible to construct a digital twin of an individual person. In other words, a âdigital doppelganger.â
Chances of âcity-destroyingâ asteroid hitting Earth have increased

Astronomers have also calculated a predicted impact zone that stretches from South America across the Atlantic Ocean to sub-Saharan Africa.
The asteroid has the potential to cause significant damage, especially if it lands in a densely populated area like a major city due to it being the size of another space rock that hit Earth in 1908 with a blast equivalent to detonating 50 million tons of TNT.
Though estimates suggest a very small increase in the likelihood of impact, astronomer and professor of planetary sciences at the Massachusetts Institute of Technology (MIT) Richard P Binzel told DailyMail.com that it is nothing to worry about.
