Seventeen years ago, Steve Jobs introduced the iPhone, a revolutionary device that combined an iPod, a telephone, and an Internet browser in one. At $500, it was expensive, but its innovation justified the cost, despite some initial flaws. Fast forward to today, and my experience with Apple’s new $3,500 Vision Pro headset has been less than stellar. This ski-goggle-style virtual reality headset aims to merge the physical and digital worlds. Apple bills it as a “space computer” designed for work, entertainment, and play. Without an advance review unit from Apple, I purchased the Vision Pro myself. With essential add-ons like…

In Japan, engineers are working to create robots that can mimic human expressions, particularly smiles. They developed a face mask using human skin cells, which they attached to robots using a new technique that hides the bond and is flexible enough to form expressions such as a grimace or a slight smile. The look is a mix between the disturbing Hannibal Lecter mask and the claymation character Gumby. However, scientists believe that these prototypes could lead to more advanced robots. These robots would have a durable, elastic outer layer that protects the machine while making it more human-like. The “skin…

On Tuesday, Nvidia leapfrogged two of the tech industry's most storied names to become the world's most valuable public company, according to data from S&P Global. Its rise has been fueled by the boom in generative artificial intelligence and growing demand for the company's chips – known as graphics processing units, or GPUs – that have made it possible to create artificial intelligence systems. Nvidia's rise is among the fastest in the history of the market. Just two years ago, the company's market valuation exceeded $400 billion. Now, in the space of a year, it has gone from $1 trillion…

The Supreme Court ruled in favor of the Biden administration in a case involving social media, scoring a significant practical victory. The ruling rejected a Republican challenge that sought to prevent the government from communicating with social media platforms to combat misinformation. In a 6-3 decision, the Court found that the plaintiffs, including states and individuals, had not suffered direct harm that would have entitled them to sue. This decision leaves unanswered broader questions about the First Amendment's limits on government influence over tech companies, which control much of the flow of information online. The case arises from the government's…

Tech giants such as Apple, Google and Microsoft are racing to develop smartphones and computers powered by artificial intelligence (AI). These devices promise to make our lives easier by automating tasks like editing photos or scheduling meetings. But there's a problem: they require a lot of data from us. More data, more convenience, less privacy? These new AI capabilities come at the cost of increased data collection. The companies envision Windows PCs taking screenshots every few seconds, iPhones merging data from various apps, and Android phones analyzing calls in real time to detect scams. This raises privacy concerns. To offer…
