AirPods 4 are dominating Amazon this June and both Active Noise Cancellation (ANC) models and the non-ANC models of the new wireless earbuds are priced lowest ever. The non-ANC AirPods 4 currently cost $99 which is a price reduction from their initial price of $129. Meanwhile, ANC-packed high-end model with transparency mode and adaptive audio costs $148 compared to $179. See AirPods Without ANC at Amazon See AirPods With ANC at Amazon Same But Different The two devices only differ in their
This article was written by an actual, flesh-and-blood human -- me -- but an increasing amount of the text and video content you come across online is not. It's coming from generative AI tools, which have gotten pretty good at creating realistic-sounding text and natural-looking video. So, how do you sort out the human-made from the robotic? The answer is more complicated than that urban legend about the overuse of em-dashes would have you believe. Lots of people write with an (over)abundance o
Nnamdi Emelifeonwu was always curious about what work life was like for his colleague Feargus MacDaeid, one of the few registered blind lawyers in the U.K. Both practiced law at the global firm Freshfields. When asking about what would make his life easier, the answer was clear: “Help me navigate definitions in complex contracts without losing context,” Emelifeonwu told TechCrunch. He realized the fix to MacDaeid’s request would be useful to every lawyer. So in 2017, Emelifeonwu and MacDaeid t
Warp was founded in 2021 to help companies streamline their shipping supply chains and reduce costs through its tech-enabled network of shippers, carriers and warehouses. Now, it wants to make supply chains further efficient by using robots to automate its web of warehouses. Daniel Sokolovsky, the co-founder and CEO of Warp, told TechCrunch that Warp is always looking for ways to make shipping more efficient for its customers, which include enterprises like Walmart, Gopuff, and HelloFresh.

What just happened? In the heart of Oregon's Silicon Forest, a group of veteran chip architects has traded the security of a tech giant for the high-stakes world of startups, aiming to redefine the future of microprocessors. The founders of AheadComputing, who collectively spent nearly a century at Intel, are now channeling their expertise into building a new class of CPU, one they believe could upend the industry's established order. Rather than building on the legacy of x86, the team is betti
Meta sues app-maker as it cracks down on 'nudifying' 2 hours ago Share Save Tom Gerken Technology reporter Share Save Getty Images Meta has taken legal action against a company which ran ads on its platforms promoting so-called "nudify" apps, which typically using artificial intelligence (AI) to create fake nude images of people without their consent. It has sued the firm behind CrushAI apps to stop it posting ads altogether, following a cat-and-mouse battle to remove them over a series of mo

In 2007, Luke Arrigoni, an AI entrepreneur, earned $63,000 at his first job as a junior software developer. Today, he says AI tools that write better code than he did back then cost just $120 annually. The numbers don’t sit right with him. Arrigoni, who runs Loti AI, a company that helps Hollywood stars find unauthorized deepfakes, worries that underpriced AI tools encourage companies to eliminate entry-level roles. He wants to flip the incentive structure so people’s careers don’t end before t
A central premise of robotaxis is that high usage and lower labor costs will ultimately make it a cheap transportation option. That is still far from true, but now there’s some data that gives us an idea of by how much. Obi, an app that aggregates real-time pricing and pick-up times across multiple ride-hailing services, has just published what it’s calling the “first in-depth examination of Waymo’s pricing strategy.” The company found Waymo’s self-driving car rides to be consistently more expe
Two European journalists were hacked using government spyware made by Israeli surveillance tech provider Paragon, new research has confirmed. On Thursday, digital rights group The Citizen Lab published a new report detailing the results of a new forensic investigation into the iPhones of Italian journalist Ciro Pellegrino and an unnamed “prominent” European journalist. The researchers said both journalists were hacked by the same Paragon customer, based on evidence found on the two journalists’
When Daniel Saks was working as a co-CEO of the previous startup he co-founded, AppDirect, billionaire Michael Dell sent him a LinkedIn message asking for a meeting. Dell famously likes to cold-contact founders of startups he finds interesting. “I thought it was fake,” Saks tells TechCrunch. But he replied anyway. “So I’m getting ready for this call, thinking there’s no way it’s Michael Dell. And I’m almost kind of laughing about it. It actually was Michael.” That interaction taught him a less

Shaquille O'Neal's long-running legal issues over his promotion of the now-bankrupt crypto exchange FTX appear to have ended. The former NBA star has agreed to pay $1.8 million to settle claims that he misled investors. In November 2022, a class action lawsuit was launched by investor Edwin Garrison against FTX founder Sam Bankman-Fried, claiming he misled customers and cost inv

Sinology | Moment | Getty Images With the U.S. restricting China from buying advanced semiconductors used in artificial intelligence development, Beijing is placing hopes on domestic alternatives such as Huawei. The task has been made more challenging by the fact that U.S. curbs not only inhibit China's access to the world's most advanced chips, but also restrict availing technology vital for c
If the U.S. continues to impose AI semiconductor restrictions on China, then chipmaker Huawei will take advantage of its position in the world's second-largest economy, Nvidia CEO Jensen Huang told CNBC Thursday. "Our technology is a generation ahead of theirs," Huang told CNBC at the sidelines of the Viva Technology conference in Paris. However, he warned that: "If the United States doesn't want to partake, participate in China, Huawei has got China covered, and Huawei has got everybody else co
Meta is suing a company that ran ads on its services to promote an app that lets people create non-consensual, sexualized images of others using AI technology, the social media company said Thursday. The lawsuit is against Joy Timeline HK Limited, which develops the app called CrushAI and its variants. The Hong Kong-based company ran ads on Facebook and Instagram to promote CrushAI, an app that uses artificial intelligence to take a photo of someone and create nude imagery of them. Meta filed
The flash crash is probably the most well-known example of the dangers raised by agents—automated systems that have the power to take actions in the real world, without human oversight. That power is the source of their value; the agents that supercharged the flash crash, for example, could trade far faster than any human. But it’s also why they can cause so much mischief. “The great paradox of agents is that the very thing that makes them useful—that they’re able to accomplish a range of tasks—
Andy Walker / Android Authority Google has pumped out so many AI products in recent years that I’d need my fingers, toes, and the digits of several other people to keep count. Its current public-facing headliner is Gemini, which also doubles as its virtual assistant on its myriad products. But, if you’re willing to lift its development rock to peek at the creepy crawlies beneath, you’ll find AI Edge Gallery. Hidden away on GitHub — where few Google-made products have ever resided — AI Edge Gal
Meta is finally cracking down on "nudify" apps that use AI to generate nonconsensual nude and explicit images of celebrities, influencers and others. The company is suing one app maker that's frequently advertised such apps on Facebook and Instagram, and taking new steps to prevent ads for similar services. The crackdown comes months after several researchers and journalists have raised the alarm about such apps. A recent report from CBS News identified at least "hundreds" of ads on Meta's plat

Agentic Coding Recommendations There is currently an explosion of people sharing their experiences with agentic coding. After my last two posts on the topic, I received quite a few questions about my own practices. So, here goes nothing. Preface For all intents and purposes, here's what I do: I predominently use Claude Code with the cheaper Max subscription for $100 a month . That works well for several reasons: I exclusively use the cheaper Sonnet model. It's perfectly adequate for my needs,
What happens inside your brain when you hear a steady rhythm or musical tone? According to a new study from Aarhus University and the University of Oxford, your brain doesn't just hear it -- it reorganizes itself in real time. Every beep, tone and new sound you hear travels from the ear to registering in your brain. But what actually happens in your brain when you listen to a continuous stream of sounds? A new study from Aarhus University and University of Oxford published in Advanced Science r
The job hunt struggle is real. Jeffrey Hazelwood/CNET Since getting laid off from a tech marketing role last November, Stephanie Wandell has applied to hundreds of jobs. She's heard back from only a handful of recruiters, without any offers. "I was a little bit naive going into it, thinking I could do what I always do and depend on applying to as many places as I can," said Wandell. "It became pretty clear that this time is different." Ask anyone who's unemployed and they'll tell you today's
In the messy world of AI image generators, there are a lot of things that can go wrong when you're trying to get the image you see in your head to appear on your screen. I've spent the past year testing and reviewing different AI image generators, and I've generated hundreds of images across services like Midjourney and Dall-E. But they haven't all been winners. A bunch of them have been downright horrifying. But it taught me that the best way to avoid creating a wonky AI image is using a good p
Google's latest budget phone, the $499 Pixel 9A, arrived fresh off the heels of Apple's "affordable" offering, the $599 iPhone 16E. Very convenient timing. The Pixel 9A is $300 cheaper than the baseline Pixel 9 and therefore scales back when it comes to features like cameras and RAM. But it maintains other attributes, like display size, processor and AI features -- and even touts a higher battery capacity than its pricier Pixel counterparts. For more on what the new phone has in store, be sure
In a $30 million mansion perched on a cliff overlooking the Golden Gate Bridge, a group of AI researchers, philosophers, and technologists gathered to discuss the end of humanity. The Sunday afternoon symposium, called “Worthy Successor,” revolved around a provocative idea from entrepreneur Daniel Faggella: The “moral aim” of advanced AI should be to create a form of intelligence so powerful and wise that “you would gladly prefer that it (not humanity) determine the future path of life itself.”
On a 5K screen in Kirkland, Washington, four terminals blur with activity as artificial intelligence generates thousands of lines of code. Steve Yegge, a veteran software engineer who previously worked at Google and AWS, sits back to watch. “This one is running some tests, that one is coming up with a plan. I am now coding on four different projects at once, although really I’m just burning tokens,” Yegge says, referring to the cost of generating chunks of text with a large language model (LLM)

On Wednesday, acting FAA administrator Chris Rocheleau told the House Appropriations Committee that the Federal Aviation Administration plans to replace its aging air traffic control systems, which still rely on floppy disks and Windows 95 computers, Tom's Hardware reports. The agency has issued a Request for Information to gather proposals from companies willing to tackle the massive infrastructure overhaul. “The whole idea is to replace the system. No more floppy disks or paper strips,” Roche
