Last week, I was ushered by an Apple employee through a security gate, past a manicured lawn, down a flight of stairs and into a tastefully decorated faux living room inside the Steve Jobs Theater to get a preview of the company’s new Vision Pro headset.My demo, like the early tours of the Vision Pro given to other reporters, was far from exhaustive. I spent about 45 minutes wearing the device under the supervision of two watchful Apple employees, who guided me through a curated demo while I sat on a midcentury gray sofa next to them. I wasn’t allowed…

In the spring of 2020, when President Donald J. Trump wrote messages on Twitter warning that increased reliance on mail-in ballots would lead to a “rigged election,” the platform ran a corrective, debunking his claims.“Get the facts about mail-in voting,” a content label read. “Experts say mail-in ballots are very rarely linked to voter fraud,” the hyperlinked article declared.This month, Elon Musk, who has since bought Twitter and rebranded it X, echoed several of Mr. Trump’s claims about the American voting system, putting forth distorted and false notions that American elections were wide open for fraud and illegal voting by…

The genetic testing company 23andMe is being accused in a class-action lawsuit of failing to protect the privacy of customers whose personal information was exposed last year in a data breach that affected nearly seven million profiles.The lawsuit, which was filed on Friday in federal court in San Francisco, also accused the company of failing to notify customers with Chinese and Ashkenazi Jewish heritage that they appeared to have been specifically targeted, or that their personal genetic information had been compiled into “specially curated lists” that were shared and sold on the dark web.The suit was filed after 23andMe submitted…

David L. Mills, an internet pioneer who developed and, for decades, implemented the timekeeping protocol used by financial markets, power grids, satellites and billions of computers to make sure they run simultaneously, earning him a reputation as the internet’s “Father Time,” died on Jan. 17 at his home in Newark, Del. He was 85.His daughter, Leigh Schnitzler, confirmed the death.Dr. Mills was among the inner circle of computer scientists who in the 1960s through the ’90s developed Arpanet, a relatively small network of linked computers located at academic and research institutions, and then its globe-spanning successor, the internet.It was challenging…

Tesla’s profit from sales of electric cars slumped in the last three months of last year because of price cuts intended to thwart increasingly intense competition, the company said on Wednesday as it warned of a tough year ahead.Profit in the fourth quarter nearly doubled to $7.9 billion, up from $3.7 billion a year earlier. But $5.9 billion of that profit came from a tax benefit. Without that one-time accounting effect, profit would have fallen.Tesla has slashed prices for the two cars that make up the bulk of its sales — the Model 3 sedan and the Model Y sport…

When Augustin Lignier, a professional photographer in Paris, was in graduate school, he began to ponder the point of picture-taking in the modern world: Why did so many of us feel compelled to photograph our lives and share those images online?It was not a novel question, but it led Mr. Lignier to a surprising place, and before long he found himself building what was, in essence, a photo booth for rats.He took inspiration from B.F. Skinner, the famous behaviorist who had devised a test chamber to study learning in rats. The Skinner box, as it became known, dispensed food pellets…

When Apple released the Apple Watch in 2015, it was business as usual for a company whose iPhone updates had become cultural touchstones. Before the watch went on sale, Apple gave early versions of it to celebrities like Beyoncé, featured it in fashion publications like Vogue and streamed a splashy event on the internet trumpeting its features.But as Apple prepared to sell its next generation of wearable computing, the Vision Pro augmented reality device, it marched far more quietly into the consumer marketplace.The company said in a news release this month that sales of the device would begin Friday. No…
