Imagine what happens if jobs actually start disappearing. Steve Bannon and Bernie Sanders don't agree on much. But both think that AI is a disaster for the working class. The Vermont senator recently wrote that "AI oligarchs do not want to just replace specific jobs. They want to replace workers."

As slick, machine-generated visuals become ubiquitous, artists and designers are embracing a style of handmade imperfection. Two and a half years ago, Christine Tyler Hill, a designer and artist in Burlington, Vermont, began working as a crossing guard in her neighborhood. The city paid her twenty dollars an hour, but the real draw was the chance to get to know local families and "be more enmeshed with my very immediate, outside-my-door community," she told me recently. She was tired of staring at a screen doing design work, and new clients were getting harder to come by, in part, she surmised, because of the rise of generative artificial intelligence . She began documenting her crossing-guard shifts on Instagram, posting mini comics about the frigid weather, the charming habits of commuting children, and the beauty of an overflowing trash can.

However, the activations of well-fitting KANs tend to exhibit pathologically high-curvature oscillations, making them difficult to interpret, and standard regularization penalties do not prevent this. Here we derive a basis-agnostic curvature penalty and show that penalized models can maintain accuracy while achieving substantially smoother activations. Accounting for how function composition shapes curvature, we prove an upper bound on the full model's curvature relative to the curvature penalty, and use this to motivate richer forms of penalties. Scientific machine learning is increasingly bottlenecked by the trade-off between accuracy and interpretability. Results such as ours that improve interpretability without sacrificing accuracy will further strengthen KANs as a practical tool for both prediction and insight.

Early childhood experts say excessive screen time displaces hands-on learning and peer interaction critical to development.

Poodle crossbreeds have grown overwhelmingly popular, sparking controversy in dog parks and kennel clubs alike. The features of doodles such as Peaches (above), a goldendoodle, have become the canine equivalent of Instagram face. Meet the Breeds, the American Kennel Club's annual showcase of purebred dogs, took place over two eye-wateringly cold days in early February at the Javits Center, in Manhattan. About a hundred and fifty of the two hundred and five varieties recognized as official breeds by the A.K.C., the long-standing authority in the U.S. dog world, were in attendance for the public to ogle, fondle, and coo "So cute!" to, including the basset fauve de Bretagne, a hunting hound from France that's one of three newly recognized breeds recently allowed into the purebred pantheon. Some of the dogs had competed in the Westminster Kennel Club Dog Show earlier in the week, and past champions had their ribbons on display. In spite of the frigid weather, pavilions hosting the more popular breeds--the pug, the Doberman pinscher, the Great Dane, the St. Bernard--were packed. Lesser-known varieties, such as the saluki, the Löwchen, and the Lapponian herder, drew sparser crowds. There were exhibition spaces for each breed, and on the back walls were three adjectives supposedly describing that particular type of dog's temperament. There is, in fact, no evidence that temperament is consistent within a breed, but the idea is deeply rooted in dogdom. I stopped to caress the velvety ear leather of a pharaoh hound ("Friendly, Smart, Noble"), a sprinting breed once used to hunt rabbits in Malta; accept kisses from a Portuguese water dog, bred to assist with retrieving tackle ("Affectionate, Adventurous, Athletic"); and have my photograph taken with a Leonberger, a German breed from the town of Leonberg, in southwest Germany ("Friendly, Gentle, Playful"). No one was supposed to be openly selling dogs, but, if you asked, the breeders would share their information. Excluding what are known as companion dogs, like the Leonberger, most of the animals at the show were designed for a purpose that is no longer required of them. In Great Britain, foxhounds are legally barred from chasing foxes. Consider the fate of the otterhound, an ancient variety with a noble heritage which was once used in the U.K. to hunt river otters, which were prized for their thick fur and disliked by wealthy landowners because they ate fish in their stocked ponds.

This happened as generative and agentic systems became essential in key sectors worldwide. This feature highlights the major AI ethics and policy developments of 2025, and concludes with a forward-looking perspective on the ethical and policy challenges likely to shape 2026.

Many fields collect large-scale temporal data through repeated measurements (trials), where each trial is labeled with a set of metadata variables spanning several categories. For example, a trial in a neuroscience study may be linked to a value from category (a): task difficulty, and category (b): animal choice. A critical challenge in time-series analysis is to understand how these labels are encoded within the multi-trial observations, and disentangle the distinct effect of each label entry across categories. Here, we present MILCCI, a novel data-driven method that i) identifies the interpretable components underlying the data, ii) captures cross-trial variability, and iii) integrates label information to understand each category's representation within the data. MILCCI extends a sparse per-trial decomposition that leverages label similarities within each category to enable subtle, label-driven cross-trial adjustments in component compositions and to distinguish the contribution of each category. MILCCI also learns each component's corresponding temporal trace, which evolves over time within each trial and varies flexibly across trials. We demonstrate MILCCI's performance through both synthetic and real-world examples, including voting patterns, online page view trends, and neuronal recordings.

Reid Hoffman Wants Silicon Valley to'Stand Up' Against the Trump Administration The LinkedIn cofounder and frequent Trump target has a simple message for his peers: "Just speak up about the things that you think are true." Reid Hoffman doesn't do much in half measures. He cofounded LinkedIn, of course, and helped bankroll companies including Meta and Airbnb in their startup days. He has also fashioned himself, via books, podcasts, and other public appearances, as something of a public intellectual--a pro-capitalist philosopher who still insists that tech can be a force for good. Most recently, Hoffman has emerged as one of Silicon Valley's most prominent defenders of artificial intelligence . His newest book, 2025's, makes the case that AI won't diminish human capacity but will instead amplify it. Hoffman even relied on AI to make one of the most unconventional--and perhaps uncomfortable, depending on your view of AI-generated creativity--Christmas gifts I've heard of lately. Whatever you think of Hoffman's utopian views on AI, credit where due: He's also a very outspoken critic of President Trump--a rare trait in a tech world that's grown increasingly quiet, or cozy, when it comes to the cruelties of the US administration. Hoffman's overt political views haven't been without consequence: Trump has twice threatened to launch investigations into him, most recently calling on Attorney General Pam Bondi to dig into Hoffman's ties to Jeffrey Epstein . He has subsequently called for the government to release the Epstein files in full.) Despite those threats, Hoffman isn't pulling punches: When we sat down to tape this episode in mid-December, he readily called out the administration for degrading American government, criticized his peers for keeping their heads down, and urged Silicon Valley to stop pretending that neutrality is a virtue. If only more billionaires were saying it. So glad to have you here. I'm glad to be here. We like to start these conversations with some very fast questions. What's the hardest lesson you've ever had to learn? Probably when to give up.

Race Against Rot shows how engaging with community may be a valuable resource. Breakthroughs, discoveries, and DIY tips sent every weekday. New research gathered with the help of a free-to-play video game indicates most people are happy to help their fellow neighbors, even if it costs them a bit of cash. According to the designers of Race Against Rot, their social experiment suggests that some new strategies to address longstanding issues facing both small-scale farmers and their nearby communities could be beneficial. Environmentalists and sustainable food system advocates alike have long stressed the importance of supporting small farms, but it's easier said than done.
