  • Is the 'Death of Reading' Narrative Wrong?
    by EditorDavid on 07/02/2026 at 11:12 pm

    Has the rise of hyper-addictive digital technologies really shattered our attention spans and driven books out of our culture? Maybe not, argues social psychologist Adam Mastroianni (author of the Substack Experimental History): As a psychologist, I used to study claims like these for a living, so I know that the mind is primed to believe narratives of decline. We have a much lower standard of evidence for "bad thing go up" than we do for "bad thing go down." Unsurprisingly, then, stories about the end of reading tend to leave out some inconvenient data points. For example, book sales were higher in 2025 than they were in 2019, and only a bit below their high point in the pandemic. Independent bookstores are booming, not busting; at least 422 new indie shops opened in the United States last year alone. Even Barnes & Noble is cool again. The actual data on reading, meanwhile, isn't as apocalyptic as the headlines imply. Gallup surveys suggest that some mega-readers (11+ books per year) have become moderate readers (1-5 books per year), but they don't find any other major trends over the past three decades. Other surveys document similarly moderate declines. For instance, data from the National Endowment for the Arts finds a slight decrease in the percentage of U.S. adults who read any book in 2022 (49%) compared to 2012 (55%). And the American Time Use Survey shows a dip in reading time from 2003 to 2023. Ultimately, the plausibility of the "death of reading" thesis depends on two judgment calls. First, do these effects strike you as big or small...? The second judgment call: Do you expect these trends to continue, plateau, or even reverse...? There are signs that the digital invasion of our attention is beginning to stall. We seem to have passed peak social media — time spent on the apps has started to slide. App developers are finding it harder and harder to squeeze more attention out of our eyeballs, and it turns out that having your eyeballs squeezed hurts, so people aren't sticking around for it... Fact #2: Reading has already survived several major incursions, which suggests it's more appealing than we thought. Radio, TV, dial-up, Wi-Fi, TikTok — none of it has been enough to snuff out the human desire to point our pupils at words on paper... It is remarkable, even miraculous, that people who possess the most addictive devices ever invented will occasionally choose to turn those devices off and pick up a book instead. The authors mocks the "death of reading" hypothesis for implying that all the world's avid readers "were just filling time with great works of literature until TikTok came along."

  • Waymo Reveals Remote Workers In Philippines Sometimes Advise Its Driverless Cars
    by EditorDavid on 07/02/2026 at 9:41 pm

    Waymo surprised U.S. lawmakers Wednesday during a hearing on autonomous vehicles and their safety and oversight. Newsweek reports: During questioning, Sen. Ed Markey, a Massachusetts Democrat, asked what happens when a Waymo vehicle encounters a driving situation it cannot independently resolve. "The Waymo phones a human friend for help," Markey explained, adding that the vehicle communicates with a "remote assistance operator." Markey criticized the lack of public information about these workers, despite their role in vehicle safety... [Dr. Mauricio Peña, chief safety officer at Waymo] responded by clarifying the scope of the operators' involvement: "They provide guidance, they do not remotely drive the vehicles," Peña said. "Waymo asks for guidance in certain situations and gets input, but Waymo is always in charge of the dynamic driving task," according to EVShift. Pressed further on where those operators are located, Peña told lawmakers that some are based in the United States and others abroad, though he did not have an exact breakdown. After additional questioning, he confirmed that overseas operators are located in the Philippines... The disclosure prompted sharp criticism from Markey, who raised concerns about security and labor implications. "Having people overseas influencing American vehicles is a safety issue," he said. "The information the operators receive could be out of date. It could introduce tremendous cyber security vulnerabilities," according to People. Markey also pointed to job displacement, noting that autonomous vehicles already affect taxi and rideshare drivers in the U.S. Waymo defended the practice in comments to People, saying the use of overseas staff is part of a broader effort to scale operations globally. Waymo also defended the remote workers to Newsweek as licensed drivers reviewed for "driving-related convictions" and other traffic violations who are also "randomly screened for drug use."

  • Good News: We Saved the Bees. Bad News: We Saved the Wrong Ones.
    by EditorDavid on 07/02/2026 at 8:34 pm

    Despite urgent pleas to Americans to save the honeybees, "it was all based on a fallacy," writes Washington Post columnist Dana Milbank. "Honeybees were never in existential trouble. And well-meaning efforts to boost their numbers have accelerated the decline of native bees that actually are." "Suppose I were to say to you, 'I'm really worried about bird decline, so I've decided to take up keeping chickens.' You'd think I was a bit of an idiot," British bee scientist Dave Goulson said in a video last year. But beekeeping, he went on, is "exactly the same with one key difference, which is that honeybee-keeping can be actively harmful to wild-bee conservation." Even from healthy hives, diseases flow "out into wild pollinator populations." Honeybees can also outcompete native bees for pollen and nectar, Milbank points out, and promote non-native plants "at the expense of the native plants on which native bees thrive." Bee specialist T'ai Roulston at the University of Virginia's Blandy Experimental Farm here in Boyce warned that keeping honeybees would "just contribute to the difficulties that native bees are having in the world." And the Clifton Institute's Bert Harris, my regular restoration ecology consultant in Virginia, put it bluntly: "If you want to save the bees, don't keep honeybees...." Before I stir up a hornet's nest of angry beekeepers, let me be clear: The save-the-pollinator movement has, overall, been enormously beneficial over the past two decades. It helped to get millions of people interested in pollinator gardens and wildflower meadows and native plants, and turned them against insecticides. A lot of honeybee advocacy groups promote native bees, too, and many people whose environmental awakening came from the plight of honeybees are now champions of all types of conservation... But if your goal is to help pollinators, then the solution is simple: Don't keep honeybees... The bumblebees, sweat bees, mason bees, miner bees, leafcutters and other native bees, most of them solitary, ground-nesting and docile, need your help. Honeybees do not. The article calls it "a cautionary tale about the unintended consequences that emerge when we intervene in nature, even with the best of intentions." Read more of this story at Slashdot.

  • Bitcoin Dropped Nearly 30% This Week. But Why?
    by EditorDavid on 07/02/2026 at 7:34 pm

    Last Sunday, Bitcoin had dropped 13% in three days, to $76,790. By Thursday it had dropped another 21%, to $60,062. This morning it's at $69,549 — up from Thursday, down from Sunday, but 44% lower than its all-time high in October of $123,742. In short, Bitcoin "is down almost 30% this week alone," reports CNBC: "This steady selling in our view signals that traditional investors are losing interest, and overall pessimism about crypto is growing," Deutsche Bank analyst Marion Laboure said Wednesday in a note to clients. Growing investor caution comes as many of the sensationalized claims about bitcoin have failed to materialize. The token has largely traded in the same direction as other risk-on assets, such as stocks... and its adoption as a form of payment for goods and services has been minimal... While many in the crypto market have previously credited large institutional investors with supporting the price of bitcoin, now it is those same participants who appear to be selling. "Institutional demand has reversed materially," CryptoQuant said in a report on Wednesday. But not everyone accepts that answer, the Wall Street Journal reported Saturday. "The worst part for some of crypto's permabulls is that they aren't sure what exactly caused the crash": The selloff left many of the market's luminaries — those so well-known that they go simply as "Pomp" and "Novo" and "Mooch" — searching for answers... Ether dropped 24% to $2,052, off 59% from its own high of last year. Both tokens staged furious rallies Friday, but the week remained a historically bad one for crypto. And few seem to know what went wrong. Market theories for the selloff ranged from investors' pivot toward the prediction markets and other risky bets, to widespread profit-taking after a blistering bull run. "There was no smoking gun," said Michael Novogratz, who runs Galaxy Digital, a crypto merchant-banking and trading firm... "If you ask five experts, you'll get five explanations," said Anthony Scaramucci, who served for 11 days as communications director during Trump's first term and is among the best-known crypto bulls at his firm, SkyBridge Capital. "No, but seriously: What's going on with bitcoin?" reads the headline at CNN, with a story that begins "Bitcoin is acting weird... " Crypto is notoriously volatile, and it's gone through numerous crashes that are bigger than this one. What's strange is this: Bitcoin's four-month slump has come at a time when, in theory, it had everything going for it. Economist Paul Krugman points out the price of Bitcoin is now lower than it was before America's 2024 election, when candidate Trump promised to make cryptocurrency "one of the greatest industries on earth." CNN seems to agree with CNBC that what's behind this new crypto winter is "Mostly doubts that bitcoin is 'digital gold,' after all..." Thanks to Slashdot reader fjo3 for sharing the news.

  • Firefox Announces 'AI Controls' To Block Its Upcoming AI Features
    by EditorDavid on 07/02/2026 at 6:34 pm

    The Mozilla executive in charge of Firefox says that while some people just want AI tools that are genuinely useful, "We've heard from many who want nothing to do with AI..." "Listening to our community, alongside our ongoing commitment to offer choice, led us to build AI controls." Starting with Firefox 148, which rolls out on Feb. 24, you'll find a new AI controls section within the desktop browser settings. It provides a single place to block current and future generative AI features in Firefox... This lets you use Firefox without AI while we continue to build AI features for those who want them... At launch, AI controls let you manage these features individually: — Translations, which help you browse the web in your preferred language. — Alt text in PDFs, which add accessibility descriptions to images in PDF pages. — AI-enhanced tab grouping, which suggests related tabs and group names. — Link previews, which show key points before you open a link. — AI chatbot in the sidebar, which lets you use your chosen chatbot as you browse, including options like Anthropic Claude, ChatGPT, Microsoft Copilot, Google Gemini and Le Chat Mistral. You can choose to use some of these and not others. If you don't want to use AI features from Firefox at all, you can turn on the Block AI enhancements toggle. When it's toggled on, you won't see pop-ups or reminders to use existing or upcoming AI features. Once you set your AI preferences in Firefox, they stay in place across updates... We believe choice is more important than ever as AI becomes a part of people's browsing experiences. What matters to us is giving people control, no matter how they feel about AI. If you'd like to try AI controls early, they'll be available first in Firefox Nightly. Some context from The Register It's a refreshingly unsubtle stance, and one that lands just days after a similar bout of AI skepticism elsewhere in browser land, with Vivaldi's latest release leaning away from generative features entirely. CEO Jon von Tetzchner summed up the mood, telling The Register: "Basically, what we are finding is that people hate AI..." Mozilla's kill switch isn't the end of AI in browsers, but it does suggest the hype has met resistance. When it comes to AI kill switches in browsers, Jack Wallen writes at ZDNet that "Most browsers already offer this feature. With Edge, you can disable Copilot. With Chrome, you can disable Gemini. With Opera, you can disable Aria...." Read more of this story at Slashdot.

  • Apple Plans to Allow Outside Voice-Controlled AI Chatbots in CarPlay
    by EditorDavid on 07/02/2026 at 5:34 pm

    Apple "is preparing to allow voice-controlled AI apps from other companies in CarPlay," reports Bloomberg, citing "people familiar with the matter." Bloomberg calls it "a move that will let users query AI chatbots through its vehicle interface for the first time." The company is working to support the apps in CarPlay within the coming months, said the people, who asked not to be identified because the plan hasn't been announced. The change marks a strategic shift for Apple, which until now has only allowed its own Siri assistant as a voice-control option within its popular vehicle infotainment software. With the move, AI providers such as OpenAI, Anthropic PBC and Alphabet Inc.'s Google will be able to release CarPlay versions of their apps that include a voice-control mode... The company also has launched a higher-end version of the platform, CarPlay Ultra, that lets drivers control functions like seat adjustments and climate settings directly through Apple's software. But that system is rolling out slowly and must be customized for each automaker. That means it's likely to be a niche offering. The article notes that Tesla is now working to support Apple's CarPlay.
