The case against social media is stronger than you think

The Mob, 1935, by Carl Hoeckner 1. Introduction The philosopher Dan Williams recently published two pieces on social media— “Scapegoating the Algorithm” at Asterisk Magazine, and “The Case Against Social Media is Weaker Than You Think” at his Substack. As their titles attest to, both argue that the case against social media, on epistemic and political grounds, has been considerably overstated. I recently published a lengthy essay arguing the opposite: that the case against social media has, i

These Climate Hacks to Save the Poles Could Totally Backfire

Last year, the United Nations predicted that Earth’s average temperature could rise more than 5.4 degrees Fahrenheit (3 degrees Celsius) by 2100 if we don’t reduce global emissions. That level of warming would cause catastrophic, irreversible damage to ecosystems, underscoring the urgent need to slow the pace of climate change. Still, the amount of greenhouse gases humans pump into the atmosphere continues to rise. Without sufficient progress on the emissions front, some scientists have suggest

Gear News of the Week: Veo 3 Comes to Google Photos, and Garmin Adds Satellite Comms to a Watch

Google via Julian Chokkattu A few months ago, Google debuted a feature in Google Photos that lets you convert your existing photos into short videos using generative AI. These videos introduce slight synthetic movements to your stills, so a person may appear to slightly shift around in the frame, or a picture of your sleeping pup could gain a leg twitch. This week, the company upgraded this feature with its Veo 3 video generation model, which boosts the quality of the results. To play around w

This Whoop Copycat Doesn’t Gouge You With Subscriptions

As great as having a fitness wearable that doesn’t distract you with another screen is on paper, I bet there’s one thing about gadgets like those made by Whoop that people aren’t as excited about—subscriptions. If you love what Whoop is putting down with its screenless fitness bands but don’t want to pay another subscription in perpetuity, Polar might be there to give you just what you need. As a part of IFA 2025, Polar announced the Polar Loop, which does what Whoop does and looks just as inof

Polar’s new minimalist fitness band is a subscription-free alternative to Whoop

The Best Cold-Plunge Pools in 2025—I Spent Months Testing to Find the Best

There was a time when a relaxing, hot bubble bath was all I needed to unwind, but these days my ice bath has taken precedence. And trust me, nobody is more surprised about this than I am. Like countless wellness trends before it, cold-plunge pools, ice baths, and cold-water therapy have been fueled by social media and celebrities, with Harry Styles, Lady Gaga, and David Beckham all advocates. Just as massage guns made the transition from elite recovery tools to workout essentials, cold-water th

Scientists Created an Entire Social Network Where Every User Is a Bot, and Something Wild Happened

It's no secret that social media has devolved into a toxic cesspool of disinformation and hate speech. Without any meaningful pressure to come up with effective guardrails and enforceable policies, social media platforms quickly turned into rage-filled and polarizing echo chambers with one purpose: to keep users hooked on outrage and brain rot so they can display more ads. And given the results of a recent experiment by researchers at the University of Amsterdam, they may be doomed to stay tha

After Shopify bought his last startup, Birk Jernström wants to help developers build one-person unicorns

Sam Altman and “his tech CEO friends” have a betting pool on the year we will see the first one-person billion-dollar company. The idea of a single person reaching a billion-dollar valuation for a startup would have been unthinkable without AI. But single-person, AI-first businesses have been sprouting all over the tech industry and Birk Jernström, CEO of Polar, a “monetization platform to empower one-person unicorns,” is standing by to help them get there. Polar hopes to stand out from other
