Pensioners are spending more than half of their waking hours looking at screens. And they appear to be more susceptible to misinformation and online hoaxes than younger folk. When the elderly are misled, it is everyone’s problem economist.com/leaders/2025/1…

The data centers needed to train AI can consume as much electricity as 200,000 American homes—and the race to power these digital tools is changing the physical world, Matteo Wong reports: theatlantic.com/magazine/2026/…

Major new report on global trends in mental health, out today from Sapien Labs. Data from 2.5 million people across 85 countries. Some of the most important findings: 1) Young adults used to generally have good mental health, compared to older generations. But now, in ALL countries examined, they are doing badly compared to older generations in that country. 2) "Four key factors have emerged that together predict three quarters of this effect. These are diminished family bonds, diminished spirituality, smartphones at increasingly young age, and increasing consumption of ultra-processed food." 3) The decline of young people's mental health is "most pronounced in the wealthier and more developed countries." They note that it is in such countries that smartphones are given earliest, junk food is most heavily consumed, spirituality is most diminished, and family ties are looser and often weaker. 4) "A younger age of first smartphone ownership is associated with increased suicidal thoughts, aggression, and other problems in adulthood." 5) Here is their summary of findings on early smartphone ownership: "GenZ is the first generation to grow up with a smartphone. Among this group, the younger they acquired their first smartphone in childhood, the more likely they are to have struggles as adults. These struggles extend beyond sadness and anxiety to less discussed symptoms, such as a sense of being detached from reality, suicidal thoughts, and aggression towards others. The effects arise through disruption of sleep, increased risk of exposure to harmful online content, predators, and explicit material as well as increased probabilities of cyberbullying during crucial developmental years. Excessive time spent on smartphones also diminishes the development of social cognition that requires learned interpretation of facial expressions, body language, and group dynamics. The negative impacts are particularly sharp below age 13." The report is short, accessible, and important. Read it here: sapienlabs.org/global-mind-he…

Exactly. If it simulates consciousness so well that humans believe it's conscious, what material difference does it make if it's "actually" conscious?

One of the biggest misconceptions about AI is that it is just a tool. A knife is a tool that cannot decide whether to chop salad or commit murder, whereas AI can make its own decisions without human involvement. From @nytimes piece “Where Is AI Taking Us?” – read the whole thing: bit.ly/NYT-YNH

We are facing a world where most of the words we consume are generated not by other humans, but by AI. What does that mean for the future of our species? From @nytimes piece “Where Is AI Taking Us?” – read the whole thing: bit.ly/NYT-YNH

The best-performing, most intensely drilled teenagers tend not to become true superstars as adults. According to new research, those who do make that grade, by contrast, tend not to stand out early on econ.st/4pN7zJc
