A New York-based AI startup called Hebbia says it’s developed techniques that let AI answer questions about massive amounts of data without merely regurgitating what it’s read or, worse, making up information. To help generative AI tools answer questions beyond the information in their training data, AI companies have recently used a technique called retrieval-augmented generation, or RAG. When users ask a question, RAG-powered AI typically uses a search-engine-style system to locate relevant information it has access to, whether that’s on the web or in a private database. Then, that information is fed to the underlying AI model along with the user’s query and an…

A few years ago, if you turned on the heat in an apartment in Helsinki, the energy typically came from coal. But the city’s power company shut down one coal plant in 2023, and the remaining one closed this week—four years earlier than a target set by the national government. “Within two years, we have completely phased out coal,” says Olli Sirkka, CEO of Helen, the power company, which is a subsidiary of the city. The city has one of the world’s biggest district heating systems, with a network of underground pipes filled with hot water that deliver heat to buildings. It takes a huge amount of energy to run. One large chunk of that now comes from wind power, which …

Walk into any grocery store to stock up for Halloween and you will discover that, for chocolate treats, you have two basic choices: Will it be Mars or Hershey? I often buy both, but that is beside the point. The point is that the two giants compete for market share, but both enjoy robust sales. In other words, a relatively stable duopoly defines the U.S. chocolate candy market. But it wasn’t always like this. Before the 1960s, the Hershey Chocolate Corp. reigned supreme as the undisputed chocolate king. It was in that decade that Mars went for Hershey’s jugular. Hershey Chocolate’s response brought lasting change to its candy business, the local community,…

At the Winter Olympics, skiers, bobsledders, speedskaters, and many other athletes all have to master one critical moment: when to start. That split second is paramount during competition because when everyone is strong and skilled, a moment of hesitation can separate gold from silver. A competitor who hesitates too much will be left behind—but moving too early will get them disqualified. Though the circumstances are less intense, this paradox of hesitation applies to daily life. Waiting for the right moment to cross the street, or pausing before deciding whether to answer a call from a number you don’t recognize, are daily examples of hesitation. Importantly, some ps…

Sitting on a coffee table in his Chelsea office in New York City and surrounded by framed wedding invitations on the walls, Justin McLeod is worrying about AI. Specifically, the cofounder and CEO of dating app Hinge is concerned that his users—many of whom have asked him to their weddings over the years—might fall in love with it instead of one another. McLeod has spent the greater part of the past 15 years studying the dynamics of human relationships, including what makes one person fall for another, and he sees that chatbots offer exactly what many people crave. “Why would I invest in these hard human relationships with people that are not always available …

In recent years, leading artificial intelligence labs and startups have released AI software designed for tasks of ever-growing complexity, including solving PhD-level math problems, reasoning through complex questions step-by-step, and using tools like web browsers to carry out intricate tasks. The role of AI engineers in making that happen is well-documented—and often well-compensated. But less publicized is the role of a growing army of freelance experts, from physicists and mathematicians to photographers and art critics, enlisted by companies specialized in AI training, itself a multibillion-dollar industry. Those companies say human wisdom is essential to creat…

Hurricane Melissa, which made landfall in Jamaica on Tuesday, October 28, was one of strongest hurricanes to make landfall in the Atlantic ocean ever recorded. And it was supercharged by the effects of climate change. As it approached the Caribbean, Melissa—a Category 5 storm with winds of 185 mph—moved over exceptionally warm waters. The ocean was 2.2°F (or 1.2°C) warmer than average for this time of year—conditions that were “made up to 900 times more likely by human-caused climate change,” according to the scientists at the research nonprofit Climate Central. Carbon emissions from human actions trap heat in the atmosphere, but our oceans absorb most of tha…

Last summer, The Brandtech Group CEO David Jones and creative director James Dow went to Cannes Lions to convince the industry of the power in their company’s GenAI tools. To show off what the tools could do, Jones and Dow declared they could create a brand in 59 minutes. The Brandtech Group made a spree of AI acquisitions over the past few years. The company’s crown jewel is Pencil, which it acquired in 2023. Pencil uses AI to create static and video ad creative, and as of December, it had generated more than 2.35 million ads for more than 5,000 brands, and processed $2.65 billion in media spend since 2018. Soon after the acquisition, the company launched a premium…

Greetings and thank you once again for reading Fast Company’s Plugged In—and a happy Halloween to you. Recently, I used Apple Photos to revisit the photos I took during the 2015 Thanksgiving holiday. There were some gems in there—memories I’d like to preserve forever. But there were even more images I regretted saving in the first place. You already know the ones I’m talking about. The near-duplicates of other, better photos. The blurry misfires. The shots of people with their eyelids drooping or mouths agape. The ones I accidentally took of the floor when my thumb slipped. Did I mention that the treasured pictures of loved ones remain intermingled with detrit…

I started building Simple in 2019 with a vision that one day, a digital product could help people fix their health as effectively as a human. Five years later, we turned this vision into a company with 160M in ARR, and a team of more than 150 people across multiple countries. If you only look at the highlights, my story can look like a straight line of an entrepreneur’s journey. However, getting there required me to rebuild my own thinking and habits. You see, I have ADHD, and a mind that constantly scans for what can go wrong. For years, I treated that as a bug. It only became my superpower once I learned how to direct it. That isn’t an easy journey, but these lesson…

Imagine everyone around you sounds like they’re shouting underwater. That’s my world without hearing aids—a reality I’ve hidden since I was a kid. Words reach me as a cacophony of blended vowels, forcing me to piece together meaning from your lips, your expressions, your gestures. And a year ago, if you’d told me artificial intelligence would help me finally embrace this part of myself, I would’ve laughed in your face. Let me explain. In the days before social media could connect you to “others like you” with a single swipe, I was the only kid I knew who needed hearing aids. So at a young age, I made a decision to hide this at all costs. And I became an expert at i…

For years, I’ve had a secret ambition tucked away somewhere near the back of my brain. It was to write a simple note-taking app—one that wouldn’t be overwhelmed with features and that would reflect my own mental filing system. In part, this yen stemmed from my dissatisfaction with existing notetakers. But I also saw the project as an adventure in software development that could only make me a smarter technology user. Just one thing stopped me: The formidable technical knowledge required even just to get started. I’m not an utter programming neophyte, but my skills largely atrophied after I graduated from high school and never extended much beyond writing buggy games. …

It doesn’t take long for Christer Collin and Ola Wihlborg to assemble the newest credenza from Ikea. Collin is a 42-year veteran of the company, specializing in product development. Wihlborg is one of the company’s most senior designers, having created dozens of pieces of furniture sold by the retailer since 2004. The two Swedes are lifting parts and turning hex wrenches in a second-floor conference room in Trnava, Slovakia, just outside the capital, Bratislava. This is where Inter Ikea Group (one of two Ikea parent companies) operates one of its more than 30 furniture and furnishings factories through its subsidiary, Ikea Industry, and where a sizable number of the retai…

Until recently, if you threw away an old mattress in Amsterdam, it would likely end up in an incinerator—the same way that most of the 15 million-plus mattresses thrown out in the U.S. each year end up in landfills. Now, however, around half of Dutch mattresses are recycled, and that number is growing. Some of the material is starting to be used in new mattresses, sofas, and other furniture by manufacturers like IKEA. [Photo: IKEA] In one facility near Amsterdam, a company called RetourMatras uses automated equipment to dismantle old beds, beginning with a machine called a peeler that cuts off the mattress cover so the fabric can be recycled. Then the core is s…

We all know influencing can pay well—but just how well? Philadelphia-based influencer Brandon Edelman, known online as @bran_flakezz, recently went viral on TikTok after revealing he made $768,000 last year, primarily from brand partnerships and creator funds. After taxes and expenses, he pocketed net earnings of just over $300,000. Known for his self-described “feral party content,” Edelman discussed his TikTok career on Your Rich BFF, a finance podcast hosted by Vivian Tu. “So $768,000 is the top number, 20 percent of that goes to management, so we’re down to, like, what $550k? From $550k, $200,000 of that goes to taxes,” Edelman said. “Just the way it goes. Now…

Sam Mintesnot had checked off everything she possibly could have from a long list of to-dos in preparation for the Coachella music festival. She crafted the best outfits, got her hair and nails done, booked a one-way ticket to Los Angeles and flew out on Tuesday with a spreadsheet full of ideas for videos she could post related to the festival. The only problem was that just days before the Coachella kicked off on Friday, she didn’t have a ticket — at least, not yet. Mintesnot is a content creator, and she was seeking an invitation from a brand to join them at the annual festival in Indio, California, that is sometimes called an “influencer Olympics.” She posted a…

Working in tech, I learned that technology alone doesn’t spark transformation. The people do. And people approach new technologies in wildly different ways. To be successful, companies need to adapt to that line of thinking, just like companies expect their teammates to adapt to transformative technologies, like AI. 3 TYPES OF AI ADOPTERS When we rolled out a custom-built company GPT to our 14,000 teammates several years ago, we saw three clear groups emerge. First, there was the “jump-in-with-both-feet” crowd. These are the early adopters who treat anything new like a shiny toy. Next were the skeptics who wondered how much of an impact AI would have on their d…

Bombs are falling across the Middle East as the United States and Israel try to bring Iran to heel. But while physical infrastructure is toppling in Iran, the country’s digital armies are still fighting with force. Groups linked to the Iranian regime have hit Jordanian gas firms, as well as businesses in the UAE and Qatar, as part of its Great Epic cyber offensive. Countries including the UK, whose military base in Cyprus has been hit by Iran-linked missiles, have begun warning businesses to prepare for possible Iranian cyberattacks. That raises a bigger question: How did Iran become such a formidable force in cyberwarfare, and to what end? A cyber shock to th…

Iranians have been struggling for nearly two weeks with the longest, most comprehensive internet shutdown in the history of the Islamic Republic — one that has not only restricted their access to information and the outside world, but is also throttling many businesses that rely on online advertising. Authorities shut down internet access on Jan. 8 as nationwide protests led to a brutal crackdown that activists say has killed over 4,000 people, with more feared dead. Since then, there has been minimal access to the outside world, with connectivity in recent days restored only for some domestic websites. Google also began partially functioning as a search engine, with …
