OpenAI's ChatGPT Agent Clicks "I Am Not a Robot" Button Without a Wink of Irony

Amid the launch of OpenAI's new ChatGPT Agent, Redditors found something odd: that the AI will gladly click its way through a test meant to distinguish between humans and robots — by identifying itself as the former. Spotted by Ars Technica, this hilarious — if not foreboding — occurrence was documented on the r/OpenAI subreddit, where a user posted screenshots of ChatGPT Agent "causally clicking the 'I am not a robot' button.'" As Ars notes, the screenshots were taken from inside the ChatGPT

Mark Zuckerberg says ‘developing superintelligence is now in sight,’ shades OpenAI and other firms focused on automating work

Want smarter insights in your inbox? Sign up for our weekly newsletters to get only what matters to enterprise AI, data, and security leaders. Subscribe Now After hiring away numerous top AI researchers from the likes of OpenAI, Google, and Apple and dangling multi-hundred million-dollar (or in one case, reportedly a billion-dollar) pay packages in a recruitment spree that’s shaken the tech industry, Meta co-founder and CEO Mark Zuckerberg is sharing more about his vision for “superintelligence

An EPA rule change threatens to gut US climate regulations

The proposed rule will go up for public comment, and the agency will then take that feedback and come up with a final version. It’ll almost certainly get hit with legal challenges and will likely wind up in front of the Supreme Court. One note here is that the EPA makes a mostly legal argument in the proposed rule reversal rather than focusing on going after the science of climate change, says Madison Condon, an associate law professor at Boston University. That could make it easier for the Sup

The AI Hype Index: The White House’s war on “woke AI”

Separating AI reality from hyped-up fiction isn’t always easy. That’s why we’ve created the AI Hype Index—a simple, at-a-glance summary of everything you need to know about the state of the industry. The Trump administration recently declared war on so-called “woke AI,” issuing an executive order aimed at preventing companies whose models exhibit a liberal bias from landing federal contracts. Simultaneously, the Pentagon inked a deal with Elon Musk’s xAI just days after its chatbot, Grok, spout

NordVPN joins the scam call fight on Android

Andy Walker / Android Authority TL;DR NordVPN has launched a Scam Call Protection feature for Android users in the US. It flags suspicious numbers using metadata, without listening to or storing call content. The feature works on any Android device with the NordVPN app and Premium plan. Scam calls aren’t slowing down and are getting smarter in many cases. While most modern smartphones already do a decent job of flagging suspicious numbers, NordVPN thinks it can do better. The company has jus

Apple TV+: ‘Slow Horses’ writer to leave the show after season 5

Will Smith, the writer and executive producer behind Apple TV+’s hit show Slow Horses, has confirmed his decision to step away from the series after the upcoming season 5. Here are the details. ’A good moment to hand over the show’ Smith has been with the show since the beginning, serving as its de facto showrunner and leading the adaptation of Mick Herron’s Slough House spy novels. Now, as Season 5 wraps post-production and prepares for release on September 24, Smith says it’s time to pass t

A new, faster-paced game mode is coming to Apex Legends on August 5

The next season of Apex Legends kicks off on August 5, and it will see the arrival of a new, permanent game mode. Respawn says it built Wildcard as a faster-paced alternative to the core battle royale mode. For instance, when you take out an enemy, they won't leave behind a death box. Instead, their loot will scatter around them, making it easier for you to spot and pick up an item you need or want. Another big difference here is legend stacking. You and your teammates will all be able to play

Mark Zuckerberg shares a confusing vision for AI 'superintelligence'

Mark Zuckerberg has spent the last several months and several billion dollars recruiting prominent AI researchers and executives for a new "superintelligence" team at Meta. Now, the Meta CEO has published a lengthy memo that attempts to lay out his big plan for using the company's vast resources to create "personal superintelligence." In the memo, which reads more like a manifesto than a strategic business plan, Zuckerberg explains that he's "extremely optimistic that superintelligence will hel

Flickering lights could help fight misinformation

A group of Cornell computer scientists has unveiled what they believe could be a new tool in the fight against AI‑generated video, deepfakes and doctored clips. The watermarking technique, called “noise‑coded illumination,” hides verification data in light itself to help investigators spot doctored videos. The approach, devised by Peter Michael, Zekun Hao, Serge Belongie and assistant professor Abe Davis, was published in the June 27 issue of ACM Transactions on Graphics and will be presented b

Linux PC acting up? How to check for bad blocks on a hard drive - before it's too late

synthetick / Getty Images I've had it happen before. Back when drives consisted of spinning, magnetic platters, that dreaded "tick" was a sure sign a hard drive was failing. Once upon a nightmare scenario, I waited too late and wound up losing everything on my drive. Sure, I could have recovered that data, but at a pretty high monetary cost.

5 preinstalled apps you should delete from your Samsung phone immediately

Prakhar Khanna/ZDNET Samsung phones are well known for One UI, one of the most functional and intuitive Android interfaces. While it's highly customizable, these phones often come with preinstalled bloatware. Some built-in Samsung apps, such as Wearable and Wallet, are useful within the Samsung ecosystem. However, there are at least five first-party apps that even dedicated Samsung users rarely touch. The preinstalled bloatware apps can vary by device, price, and lineup, but many are common ac

Ubuntu Linux lagging? Try my 10 go-to tricks to speed it up

Yuichiro Chino/Getty Unless you're using a computer from the '90s or early 2000s, typically speaking, Ubuntu runs very well on most machines. I've found it to be fairly predictable in that respect. However, nothing is perfect, and you might run into an instance where the open-source operating system doesn't perform up to your standards. So, what do you do? Do you hop to a different distribution? You certainly could, as there are plenty of Linux distributions that work perfectly on older hardwa

How I survived a week with this $130 smartwatch instead of my Garmin and Galaxy Ultra

Words about Arrays and Tables

July 30, 2025 2000 words about arrays and tables THEY'RE JUST FUNCTIONS I'm way too discombobulated from getting next month's release of Logic for Programmers ready, so I'm pulling a idea from the slush pile. Basically I wanted to come up with a mental model of arrays as a concept that explained APL-style multidimensional arrays and tables but also why there weren't multitables. So, arrays. In all languages they are basically the same: they map a sequence of numbers (I'll use 1..N ) to homog

Hi HN, we’re Abhinav, Andy, and Jeremy, and we’re building Lucidic AI ( https://dashboard.lucidic.ai ), an AI agent interpretability tool to help observe/debug AI agents. Here is a demo: https://youtu.be/Zvoh1QUMhXQ. Getting started is easy with just one line of code. You just call lai.init() in your agent code and log into the dashboard. You can see traces of each run, cumulative trends across sessions, built-in or custom evals, and grouped failure modes. Call lai.create_step() with any metad

Big Tech Killed the Golden Age of Programming

Big Tech Killed the Golden Age of Programming The reason it's so hard to get a programming job right now is because Big Tech caused it. It's not an accident. It's not the result of regular cycles of employment or the economy. For years, companies like Google, Facebook/Meta, and Amazon hired too many developers. They knew they were hiring too many developers, but they did it anyway because of corporate greed. They wanted to control the talent pool. They wanted to make as much money as possible,

A Rare Flu Complication Is Killing More U.S. Children

A rare, life-threatening complication caused by the flu seems to be surging among kids. Research out today finds that dozens of children developed influenza-associated acute necrotizing encephalopathy (ANE) over the past two years, a third of whom died as a result. Researchers at Stanford Medicine led the study, published Thursday in JAMA. Collecting reports from other doctors and hospitals across the country, they identified 41 cases of ANE since 2023, along with 11 deaths. The researchers arg

Physicists Catch ‘Ghost Particles’ Bouncing Off Matter in Record-Breaking Experiment

Neutrinos are everywhere. About 100 trillion neutrinos pass through our bodies every second, but they’re so weakly interacting we never notice them. It’s this spooky feature of neutrinos that earned them the nickname “ghost particles.” Antineutrinos, their antimatter counterpart, are also everywhere. Both are notoriously difficult to detect, but physicists are getting better at circumventing their ghostly tendencies, as a recent record-setting measurement demonstrates. When a low-energy neutrin

Matt Shakman Thinks What Was Cut From ‘Fantastic Four’ Was for the ‘Greater Good’

It’s been just shy of a week since Marvel’s latest installment in its ever-expanding cinematic universe, The Fantastic Four: First Steps, released in theaters. While much of the hubbub about the film is generally favorable, verging on “we’re so back,” some online fans lamented over the movie seemingly leaving a lot of content from its trailer on the cutting room floor for their liking. Now, director Matt Shakman has come forward to discuss the rigorous editing process behind the Marvel film. In

Watch a Reconstructed 250-Year-Old Robotic Painting Bring a Fiery Mount Vesuvius Back to Life

Sir William Hamilton was the British ambassador to the court of Naples and Sicily from 1765 to 1800, as well as a passionate volcanologist. During his time in Italy he must have seen Mount Vesuvius erupt a number of times—certainly enough to leave a lasting impression. So much so that in 1775 he designed a rotating device that, with mechanical movement and light, could bring to life the fiery magma depicted in Pietro Fabris’ 1771 watercolor, “Night view of a current of lava.” While experts aren

Even The Guy Who Makes ChatGPT Says You Probably Shouldn't Use Chatbots as Therapists

Maybe don't tell your deepest, darkest secrets to an AI chatbot like ChatGPT. You don't have to take my word for it. Take it from the guy behind the most popular generative AI model on the market. Sam Altman, the CEO of ChatGPT maker OpenAI, raised the issue this week in an interview with host Theo Von on the This Past Weekend podcast. He suggested that your conversations with AI should have similar protections as those you have with your doctor or lawyer. At one point, Von said one reason he w

Not (just) seeing red: Virtual Boy emulator adds full color support

Here at Ars, we're big fans of classic console emulators that go beyond providing perfect re-creations to those that actually improve on original hardware with new features we could only dream of as kids. So we were excited when we recently stumbled on a Reddit post that shows a full Super Game Boy-esque color palette added to the usual shades of red and black found in Virtual Boy Wario Land. After experiencing colorized Virtual Boy emulation for ourselves (and grabbing the sample screenshots y

How 2 UC Berkeley dropouts raised $28 million for their AI marketing automation startup

AI-powered marketing automation startup Conversion, founded five years ago by two UC Berkeley dropouts, has raised a $28 million Series A led by Abstract, with participation from True Ventures and HOF Capital. The company’s founding story sounds like it could have been an episode of the HBO show “Silicon Valley.” The story begins all the way back when co-founder and CEO Neil Tewari, now 24, was in high school.
