OpenAI Engineer Quits, Says Company Is Pure Chaos Inside

OpenAI CEO Sam Altman is setting a breakneck pace with his company, rolling out feature after feature to keep the multibillion-dollar gravy train steaming ahead. And that kind of drum beat, especially paired with ChatGPT's meteoric rise, is bound to cause plenty of chaos behind the scenes. In a blog post, former OpenAI engineer Calvin French-Owen, who helped build the company's new coding agent Codex, said there "wasn't any personal drama in my decision to leave" — but he did recap his experie

Over Half of Teens Regularly Use AI Companions. Here's Why That's Not Ideal

Is your teen using a chatbot for companionship? If you don't know, you might want to ask. Common Sense Media released a study on Wednesday, in which it found that more than half of pre-adult teenagers regularly use AI companions. Nearly a third of the teens reported that conversations with AI were as satisfying as conversations with actual humans, if not more so. Researchers also found that 33% of teens use AI companions such as Character.AI, Nomi and Replika "for social interaction and relatio

Dyneema’s New Fiber Composite Is Lighter, Stronger, and More Durable Than Ever

If you went back in time 150 years and told people that in the future they will carry everything they need to live for a week on their backs, you'd get run out of town. Carrying gear is the job of horses and mules, not people! Fast forward to the present, though, and here we are, schlepping into the backcountry with the essentials on our back. Progress! The good news is that today everything you need to live for a week weighs considerably less than it did 150 years ago. The ultralight backpacki

Samsung Galaxy Z Fold 7 Review: Foldable Perfection That’s Tempting Me to Leave My iPhone

2025 Disregard the fact that there’s a whole world of Chinese-made book-style foldables as thin and light as the Galaxy Z Fold 7 that Americans can’t buy, and Samsung’s latest phone-to-tablet foldable is what we’ve been waiting for. It only took Samsung six years to make its flagship foldable as svelte as a regular bar smartphone, but the Z Fold 7 delivers in all aspects. The only thing that holds it back is the $2,000 price tag, a $100 increase over last year’s Z Fold 6. See Galaxy Z Fold 7 a

The best free VPNs of 2025: Secure, safe, and fast VPNs

My top pick for free VPNs available in 2025 is Proton VPN, which, despite its limits, will suit many users who do not want to subscribe. Why we like it: The free version of Proton VPN offers many useful features that are paid for through other services and VPN subscribers. This is important when it comes to free VPN services, as it provides a measure of security and data protection that some shady services do not. After all, if your information is being sold in return for a VPN connection, this

What Is the Best Smart Ring for Health Tracking? I Tested 3 Popular Options to Find Out

The Oura ring was my favorite smart ring because its app was easy to understand and I liked some of the newer features from its latest software update. At the steep price of $299, this smart ring is made up of aerospace-grade titanium – one of the strongest materials on earth -- according to the site. Before I received my Oura ring, I was sent a ring sizer to figure out my ring size. Other smart rings did the same since sizing varies per brand. Once I received the Oura ring, I downloaded the Ou

A Staggering Proportion of Teens Say Talking to AI Is Better Than Real-Life Friends

A new survey found that over half of American teens are regular users of anthropomorphic AI companions like Character.AI and Replika. That's striking on its own, as an illustration of how embedded AI companions have become in mainstream teenage life. But even more startling were the 31 percent of surveyed teens who said their interactions with AI companions were either as satisfying or more satisfying than conversations with real-life friends — a finding that shows how profoundly AI is already

Finally, a smart ring that rivals my Oura 4 with no subscription fee

ZDNET's key takeaways The RingConn Gen 2 is a subscription-free smart ring that monitors sleep, exercise, and stress. It monitors your sleep, activity, stress, and vitals, and it's got a marathon battery life. The only downside is the user interface feels underdeveloped.

Enabling This One iPhone Feature Has Helped Me Get More Precious, Quality Sleep

I take sleep seriously and will honestly try anything that promises to help me get more rest. However, getting quality sleep doesn't have to involve a white noise machine or other device you have to buy with your hard-earned cash. In fact, as I discovered, it can be as simple as turning on a certain feature on your iPhone. Go figure. For the past five years, I've been getting better, longer sleep thanks to this one hidden iPhone feature. For those who also struggle with sleep and happen to have

Looking Down at Your Phone is Distressing Your Neck. Here's How to Correct Tech Neck

Do you have a job that requires lots of time at a desk, staring at a screen or looking down at a phone? If so, you could be straining more than your eyes. It can also lead to a modern problem called "tech neck." This phenomenon results from maintaining an unnatural position while looking down at a screen, and it affects everyone, from kids who play tablet games to adults who work at a desk all day. A study from 2024 found that neck pain has drastically increased among individuals who live a sede

Could 5G Home Internet Be Your Household Broadband Solution?

For most Americans, internet service providers are a constant source of stress and notoriously one of the country's lowest-rated industries. ISPs rank lower than social media, the US Postal Service and even airlines. It's not hard to see why. A recent CNET survey found 63% of Americans paid more for internet service last year than they had the year before. On top of that, wading through confusing details like hidden fees, yearly price hikes, contracts, service details and multiple speed tiers ca

Bedsure's Bamboo Cooling Sheets Are Silky Soft, Durable, and Cheap

I’ve met many supposedly “cooling” sheets in my time as a mattress and bedding tester, and I have been disappointed more often than not. A cooling mattress can’t do all the heavy lifting with temperature regulation, and I’ll forever emphasize that your choice of bedding matters just as much—which is why I'm an unapologetic sheet snob. Which brings me to Bedsure, a brand I stumbled across on Amazon in a last-ditch effort to find some decent sheets when mine bit the dust (rather, my dogs bit holes

Become a Master of Evil With Darth Vader’s Actual Lightsaber (if You Have $3 Million)

io9 has covered a few notable Star Wars auctions lately, as rare toys and highly collectible props have come to market in surprisingly robust amounts. But maybe the most exciting example has just emerged: Darth Vader’s lightsaber. The actual, authentic, screen-matched hilt used by David Prowse and his stunt double in both The Empire Strikes Back and Return of the Jedi. As your mind reels at the possibility of owning such a prize, consider that it’s estimated to command $1 million at the lowest e

Voxtral – Frontier open source speech understanding models

Voice: the original UI. Voice was humanity’s first interface—long before writing or typing, it let us share ideas, coordinate work, and build relationships. As digital systems become more capable, voice is returning as our most natural form of human-computer interaction. Yet today’s systems remain limited—unreliable, proprietary, and too brittle for real-world use. Closing this gap demands tools with exceptional transcription, deep understanding, multilingual fluency, and open, flexible deploy

These 4 Exercises May Be Key to a Good Night’s Sleep

When you’re exhausted, starting a new exercise routine may sound like a nightmare, but a new study suggests getting active could be the secret to a good night’s sleep. Scientists in China reviewed existing clinical trial data and found that certain forms of exercise, including yoga and jogging, that appeared to help people sleep longer at night. The findings suggest physical activity should be considered as a frontline treatment for insomnia, the researchers said. “The most important takeaway

We Are Having a Very Hard Time Believing the "Shape" of Tesla's New Robotaxi Geofence Is a Coincidence

Tesla has expanded the area where its Robotaxis can operate in Austin, and it's difficult — nay, impossible — to ignore its resemblance to something unmistakably vulgar. As folks immediately pointed out online, the crudely-shaped geofence is, essentially, a bathroom graffiti-level dick drawing — and given his puerile sense of humor, there's a non-zero chance that Tesla CEO Elon Musk made it that way on purpose. Indeed, after someone posted a video showing the phallic geofence on X, the shitpos

Underwriting Superintelligence

Insurance Unlocks Secure AI Progress We’re navigating a tightrope as Superintelligence nears. If the West slows down unilaterally, China could dominate the 21st century. If we accelerate recklessly, accidents will halt progress, as with nuclear power. Insurance, standards, and audits together create skin in the game for quantifying, communicating, and reducing AI risks so we can balance this tightrope. We call this the “Incentive Flywheel.” Benjamin Franklin first discovered the Incentive Fly

Human Stigmergy: The world is my task list

Marco Giancotti , July 10, 2025 Cover image: Termite mound cross-section, Wikimedia Commons Termites and ants have no central planning. There are no architect ants in a nest-building project, no sponsors or supervisors, no instructions. Each worker is unaware and completely uninterested in what form the final mega-structure will take. No blueprints are to be found in any of their minds or outside them. Yet they build them all the time, and very well, too. Their substitute for plans and bluepri
