The past few days in the stock market have been so wild—a plunge on Monday, a sharp pivot upward on Tuesday, a rise with lots of oscillations on Wednesday—that a record set by the Dow Jones Industrial Average on last week’s final day of trading has been largely overlooked. That’s unfortunate, because there’s a lot to be learned from that record about how financial markets work. I’m referring to the record loss inflicted on the Dow last Thursday by the three-digit share price drop of UnitedHealth Group (NYSE: UNH), the large healthcare and insurance company. (Thursday was the last day of trading last week because the market was closed for Good Friday.) That price d…

Three months ago, I fired up ChatGPT and asked it to design a highly aggressive, short-term investment portfolio, selecting five stocks that were most likely to make me fabulously wealthy in six month’s time. Then, I threw good sense to the wind, transferred $500 of my actual money into a Robinhood account, and bought the stocks that ChatGPT had pitched. Since then, it’s been a wild ride. My portfolio has flown to new heights, giving me serious FOMO about the fact that I didn’t put all my money into ChatGPT’s picks. Then, it singed its wings, falling Icarus-style to lows that had me almost ready to bail on the whole thing and redirect the charred rema…

How do modernist transportation planners recommend handling congestion? By recommending new vehicle lanes. What happens when you build new vehicle lanes to handle traffic congestion? The vehicle lanes fill up with more traffic congestion. As they themselves have said for decades, you cannot build your way out of congestion. But every week you can do a quick internet search to see a bunch of new attempts. ‘Induced demand’ I’ve been hearing planners and engineers say “we can’t build our way out of congestion” since the 1990s, when I began my career. The wonky term that describes why adding more lanes doesn’t eliminate congestion is “induced demand.” Transportation p…

Every December, millions of people pause to take stock of their lives before the new year. Some gather for vision-board parties, others sketch out New Year’s resolutions, and many quietly vow to “finally get organized” before the clock hits midnight. But this year feels different. We’re closing out 2025 in an economic climate defined by weekly corporate layoffs, social media posts from people with excel trackers archiving hundreds of job applications, and sidelined workers hopelessly looking for jobs for over a year. Families are being pushed to the brink by rising prices, and a generational affordability crisis—fueled by a shortage of three to four million homes nati…

The correlation between reduced crime rates and thriving communities is profound. Lower crime not only ensures the safety of residents but also sets off a chain reaction of positive outcomes that enhance the overall quality of life. In short, crime reduction touches not only the potential would-be victims and families. It also touches the entire neighborhood and community that may not even directly understand the downstream effects. We’ve observed this time and time again over the past 8 years in building Flock Safety, a technology company that builds tools to solve and reduce crime. When cities feel the impact of lower crime, it’s reflected across every aspect of dai…

As a learning designer at Zapier, I used to spend my days helping my teammates learn: I built and led trainings, created enablement resources, and helped folks better understand how their work contributed to company strategy. Now, I sit inside our HR team as an AI automation engineer. But the through line is the same: I still help my teammates (and now customers, too!) do their best work. What is an AI automation engineer? AI automation engineer sounds like a vague title, so here’s the job, plainly: I embed with a team (HR, in my case), spot opportunities to enhance the team’s work, and build AI-powered workflows that jump on those opportunities. The goal is to cre…

For the last several years, enterprises have treated AI as something to test. A pilot here, a proof of concept there. That era is ending. According to new global DeepL research, a survey of 5,000 global executives on the impact of AI agents reshaping business, 69% expect AI agents to fundamentally change how their companies operate in 2026. Nearly half anticipate major transformation, while another quarter say that change is already underway. This moment didn’t arrive overnight. While 2025 was the year agentic AI moved from theory to application, enterprises are making the shift structural this year. Leaders are no longer asking whether AI works but rather deciding wh…

The companies behind AI models are keen to share granular data about their performance on benchmarks that demonstrate how well they operate. What they are less eager to disclose is information about their environmental impact. In the absence of clear data, a number of estimates have circulated. However, a new study published in Cornell University’s preprint server arXiv offers a more accurate estimation of how AI usage affects the planet. The research team—comprised of scientists from the University of Rhode Island, Providence College, and the University of Tunis in Tunisia—developed what they describe as the first infrastructure-aware benchmark for AI inference, …

Hello again, welcome to Fast Company’s Plugged In, and a quick note: A couple of weeks ago, I mentioned a game I was vibe-coding using Claude Code, and said I would share it once I finished it. Here it is, along with more thoughts on the uncanny experience of collaborating with AI on a programming project. Late Show host Stephen Colbert and his network, CBS, are still at odds over why his planned interview with James Talarico, a Democratic candidate for a Texas U.S. Senate seat, didn’t air last Monday. In Colbert’s account, CBS lawyers forbid the broadcast after Federal Communications Commission chair Brendan Carr said talk show interviews might trigger the FCC’s …

The District of Columbia, Maryland, and Virgina (DMV) region is emerging as a national test case for the future of office space. As cities across the country grapple with persistent office vacancies, D.C. is taking a bold approach: Instead of focusing solely on residential conversions, it is pioneering a broader strategy to convert offices to…anything. While the concept of office conversions isn’t new, most efforts have been centered on residential use. D.C.’s strategy breaks that mold. In January 2025, the city launched the Central Washington Activation Projects Temporary Tax Abatement, better known as the Office to Anything program. This policy targets build…

More than 11.5 million fans signed up for presale tickets to Harry Styles’s upcoming Madison Square Garden residency for the Together, Together tour. But when tickets went on sale January 26, amid the excitement, many fans were left frustrated by lengthy virtual queue waits. For those who made it through, the relief proved fleeting when they encountered ticket prices exceeding $1,000. Many turned to social media to direct their ire at both Ticketmaster and Styles himself. “$1000 for lower bowl at msg is genuinely the most insulting thing ive ever seen. that’s one months rent,” one person posted on X. “Its getting to the point where I feel like im being f…

When the lights finally dimmed at the 2025 Victoria’s Secret Fashion Show last night, the first thing guests saw was a gold light emanating from backstage. Model Jasmine Tookes, nine months pregnant, opened the show in a gold macramé dress with drop pearls and a pearl and crystal wing in the shape of a clamshell. Art buffs might notice that the shell is a callback to Sandro Boticelli’s renaissance painting “Birth of Venus,” symbolizing sensuality, divine beauty, rebirth, and new beginnings. The cultural reference is a more elevated and considered nod to womanhood than the show’s previous themes, which have included “Santa’s Helpers” or “delicious sweets.” The loo…

The Farmers’ Almanac isn’t going out of business after all, but it is leaving Maine for the bright lights of New York City and a new owner. Beloved by farmers and gardeners, the almanac was first printed in 1818 and — like the arguably more famous Old Farmer’s Almanac — relies on a secret formula of sunspots, planetary positions, and lunar cycles to generate long-range weather forecasts. It’s been acquired by Unofficial Networks, a digital publisher focused on skiing and outdoor recreation. That means the almanac will keep operating despite announcing in November that its 208-year run was coming to an end. A new Farmers’ Almanac website will be “a living, brea…

Last Saturday, more than six million people held their breath as Alex Honnold took his first step up Taipei 101. The Free Solo climber, who went on to ascend Taiwan’s tallest building without the safety of a rope and harness, drew crowds all around the building, as well as on Netflix, where the ascent was live-streamed as part of a show called Skyscraper Live. Some of these people had likely already watched Honnold scale the 3,000-foot rock wall of Yosemite’s El Capitan. But for many, the climber’s ascent up a man-made structure was likely an introduction to an altogether different kind of climbing: not on the face of a cliff, but the side of a building. This type…
