Robert F. Kennedy Jr. is an AI guy. Last week, during a stop in Nashville on his Take Back Your Health tour, the Health and Human Services secretary brought up the technology between condemning ultra-processed foods and urging Americans to eat protein. "My agency is now leading the federal government in driving AI into all of our activities," he declared. An army of bots, Kennedy said, will transform medicine, eliminate fraud, and put a virtual doctor in everyone's pocket. RFK Jr. has talked up the promise of infusing his department with AI for months.

Roughly five years ago, Ant Group reined in its ambitions after a derailed initial public offering. Today, the Jack Ma-backed company is betting on a very different business to fuel its next phase of growth: health care powered by artificial intelligence. What began as a digital payments platform has become one of China's biggest investors in medical AI, backing software that fields patient questions and connects them with doctors, pharmacies and insurers. In November, Ant elevated its health unit to the same level as operations including Alipay and its lending businesses, underscoring how central the effort has become to the company's strategy. After years focused on consumer lending, wealth management and insurance technology, health care is now where executives believe AI can unlock the next wave of growth, leveraging Ant's massive user base to become its biggest business outside of payments.

Are you interested in learning more about the ways in which AI is being used? We've launched a new weekly newsletter series exploring just that: digging into how generative AI is being used and deployed across sectors and what professionals need to know to apply it in their everyday work. Each edition of Making AI Work begins with a case study, examining a specific use case of AI in a given industry. Then we'll take a deeper look at the AI tool being used, with more context about how other companies or sectors are employing that same tool or system. Finally, we'll end with action-oriented tips to help you apply the tool. The first edition takes a look at how AI is changing health care, digging into the future of medical note-taking by learning about the Microsoft Copilot tool used by doctors at Vanderbilt University Medical Center.

Users Like It or Not, A.I. Is Part of Health Care Now There's a key thing to keep in mind if you ask a chatbot for medical advice. Asking a general-use chatbot for health help used to seem like a shot in the dark--just two years ago, a study found that ChatGPT could diagnose only 2 in 10 pediatric cases correctly. Among Google Gemini's early recommendations were eating one small rock a day and using glue to help cheese stick to pizza . Last year, a nutritionist ended up hospitalized after taking ChatGPT's advice to replace salt in his diet with sodium bromide. Now A.I. companies have begun releasing health-specific chatbots for both consumers and health care professionals.

Others say they don't need us. It's time for us to think of ourselves not as the high priests of health care but as what we have always been: healers. Not long ago, I cared for a middle-aged man I'll call Jim, who was generally healthy but had recently started to feel sluggish. One of his friends told him to try a hormone supplement. After Jim saw on social media that Robert F. Kennedy, Jr., the Trump Administration's Secretary of Health and Human Services, had endorsed supplements as a part of an "anti-aging" regimen, he ordered one from a telehealth company. A few months later, he noticed swelling and pain in his calf. ChatGPT warned him that he might have a blood clot.

Which of These Updated Health-Care Plans Is Right for You? Thrilling news: it's time to decide what health-care plan you'll be opting in to for the coming year.

This is our most popular plan. It covers things like breathing (allowed, no co-pay), sleeping (hint: you must pretend to sleep in order to fall asleep), and eating (you pay for your own food).

The billionaire investor campaigned for Kamala Harris, but thinks tech execs have a "moral imperative" to play nice with the president. Back in May, Mark Cuban appeared in his last episode of ABC's after spending more than a decade on the show investing in--or deprecating--entrepreneurs' big ideas. But that doesn't mean the billionaire is going away. Yes, Cuban loves to talk--about ideas, about the future, about what it takes to actually make America healthy again. Or, at least, to get Americans more affordable drugs, which Cuban is endeavoring to do with his startup, Cost Plus Drug Company. Nor does Cuban, like many billionaire businessmen, shy away from talking politics: Does he like President Trump? But would he join the president for dinner like so many of his peers have in recent months? With enthusiasm, according to a conversation we had for this week's episode of . Keep reading to find out why. Just so you know--well it's too late now--we always start these conversations with some rapid-fire questions. What is the smartest investment you ever made? What's the dumbest purchase you ever made? Alright, one word to describe the startup pitches that you hate. Would you rather invest in passion or in numbers? Tell me a little bit about why.

LLMs excel at understanding nuanced context, performing instinctive reasoning, and generating human-like interactions, making them ideal for agentic tools to then interpret intricate data and communicate effectively. Yet in a domain like health care where compliance, accuracy, and adherence to regulatory standards are non-negotiable--and where a wealth of structured resources like taxonomies, rules, and clinical guidelines define the landscape--symbolic AI is indispensable. By fusing LLMs and reinforcement learning with structured knowledge bases and clinical logic, our hybrid architecture delivers more than just intelligent automation--it minimizes hallucinations, expands reasoning capabilities, and ensures every decision is grounded in established guidelines and enforceable guardrails. Ensemble's agentic AI approach includes three core pillars: The team has decades of data aggregation, cleansing, and harmonization efforts, providing an exceptional environment to develop advanced applications. To power our agentic systems, we've harmonized more than 2 petabytes of longitudinal claims data, 80,000 denial audit letters, and 80 million annual transactions mapped to industry-leading outcomes.

While everyone else has been talking about Nvidia's GPUs, Lisa Su has discreetly turned AMD into a chipmaking phenom. Su, the leader of AMD, moves fast these days, though I suspect that's always been the case. Her company's chips underpin the artificial intelligence that's changing the world at breakneck speeds. To hear Su and literally everyone else in semiconductors talk about it, the US is in an AI with China--and the rules keep changing . The Trump administration has once again shifted its stance on what kind of chips can and can't be shipped to China, with the latest decree being that the US will take a 15 percent cut of AMD and Nvidia chip sales to China. Meanwhile, on the home front, Su has claimed that AMD's newest AI chips can outperform Nvidia's--part of her strategy to keep eroding Nvidia's dominance in the market. So, yeah: Be ready to keep up. Under Lisa Su, the stalwart American semiconductor company has reasserted itself as a force in the age of AI. "Reasserted" doesn't do it justice: Su took a struggling AMD and executed a 10-year turnaround that has been, as one economist put it, nothing short of remarkable. Since 2014, when Su took over as CEO, AMD's market cap has risen from around $2 billion to nearly $300 billion. Aside from her well-known bona fides, Su herself--what drives her, what inspires her, what irritates her, where her politics lie--is less known. This is what I was hoping to learn when I visited AMD's offices and labs in the hills of Austin, Texas, on a day in late June when the wind seemed to do little more than push heat around. Our conversation kicked off with China, which accounts for nearly a quarter of AMD's business. Su now travels frequently to Washington, DC, to grease the wheels. "We've come to realize that export controls are a bit of a fact of life," she told me, "just given how critical the chips that we make are." In other words, it's precisely because AMD's chips are so darn important--to national security, to national economies--that they're now at the heart of modern statecraft.

In the much-celebrated book Deep Medicine, Eric Topol argues that the development of artificial intelligence for health care will lead to a dramatic shift in the culture and practice of medicine. In the next several decades, he suggests, AI will become sophisticated enough that many of the everyday tasks of physicians could be delegated to it. Topol is perhaps the most articulate advocate of the benefits of AI in medicine, but he is hardly alone in spruiking its potential to allow physicians to dedicate more of their time and attention to providing empathetic care for their patients in the future. Unfortunately, several factors suggest a radically different picture for the future of health care. Far from facilitating a return to a time of closer doctor-patient relationships, the use of medical AI seems likely to further erode therapeutic relationships and threaten professional and patient satisfaction.
