On with Kara Swisher

From an unenforced TikTok ban and a chatbot calling itself MechaHitler to mounting fears that we’re in an AI bubble, 2025 was another messy year for the tech industry. We watched billionaire CEOs fully align themselves with President Trump, Nvidia become the first $5 trillion company, and Elon Musk’s popularity tank, thanks to his DOGE antics (and yet he could still become the world’s first trillionaire).  Kara breaks down the biggest tech stories of 2025 with four journalists: Bill Cohan, a longtime financial journalist, author, and Puck co-founder who covers Wall Street; Casey Newton, founder and editor of the tech newsletter Platformer and host of The New York Times podcast “Hard Fork”; Joanna Stern, senior personal technology columnist for The Wall Street Journal and author of a forthcoming book about how she surrendered her life to A.I. for a year; and Charlie Warzel, staff writer at The Atlantic and host of the tech and culture podcast “Galaxy Brain.”  (Please note, this conversation was recorded before news broke that TikTok had signed a deal to spin off its U.S. business to a group of American investors, the Justice Department released a trove of documents tied to investigations into Jeffrey Epstein, and Waymo halted service in San Francisco because of power outages in the area.)  Questions?

Kara sits down with Uber CEO Dara Khosrowshahi to dig into how applied artificial intelligence works at scale.  At Uber, AI powers everything from pricing, routing, and customer service to autonomous vehicles and sidewalk robots that deliver food. It has partnered with more than 20 autonomous vehicle manufacturers, and it’s moving aggressively into robotaxis. And although it may take many decades, Khosrowshahi believes society may eventually decide humans aren’t safe enough to be trusted behind the wheel. Kara and Dara discuss what this all means for jobs, congestion, climate and Uber’s business model.  This conversation was recorded live at the Johns Hopkins University Bloomberg Center as part of its Discovery Series on artificial intelligence.   Questions?

One of 2025’s most memorable images was of Silicon Valley’s billionaire CEOs lined up in the front rows at President Donald Trump’s inauguration. It was visual proof of the tech industry’s embrace of MAGA’s authoritarian-style of politics — one it has benefited from considerably over the last year. Author and neuroscientist Sam Harris has been using his podcast, “Making Sense,” to talk about the ways tech moguls are corroding our politics, and although he used to be close with some of them, he’s become a vocal critic of their support for Trump. Kara and Sam talk about why he thinks the left is to blame for the tech billionaires’ shift to the right, why all of us are bad at sorting through the glut of information we find online, and the potential risks that come with the Trump administration’s hands-off approach to A.I. They also talk about what possible tech regulation could look like, and whether everyday people stand a chance against tech oligarchs and their platforms.  (Please note: This interview was recorded before President Trump signed an executive order to block states from passing A.I. regulation.)

Rachel Maddow is an author, podcast host and producer, documentary producer, and, of course, the anchor of her eponymous show on MS NOW. Her newest podcast, "Rachel Maddow Presents: Burn Order," unravels how the incarceration of more than 100,000 Japanese Americans and Japanese immigrants during WWII was planned and carried out. Shockingly, the full story behind one of the 20th century’s worst American human-rights abuses might never have come to light if not for the relentless work of a hobbyist researcher — who had been incarcerated herself. Kara and Rachel dig into the story and explore the parallels to President Trump’s mass-deportation policies. They also discuss the recent boat strikes on alleged drug traffickers, the escalating drama around the competing bids for Warner Bros. Discovery and what it signals for the future of the news business, and MSNBC’s evolution into MS NOW. Please note: This episode was taped on Tuesday, before President Trump said it was “imperative that CNN be sold." Questions? Comments?

Margaret Atwood is one of the most famous and prolific authors of the modern era. Though best known for her 1985 hit “The Handmaid’s Tale,” her dozens of works span literary genres — poetry, novels, children's books, essays, short stories — and often defy neat categorization. Now, at 86, Atwood has written her first memoir. At roughly 600 pages, it’s an intimate look at the ways her personal life inspired and shaped her writing.  Kara and Atwood talk about her lifelong passion for the outdoors, how she decided to become a poet when she was just a teenager, and her reputation for having an eerie prescience about major world events. They also talk about Atwood’s fears about the Trump administration’s use of power, and why she still considers herself to be a hopeful person despite her predilection for dark stories.  Questions?
