Why Is It So Hard to Make a Good Weather App?

How are we still getting caught in the rain? This week’s “Galaxy Brain” explores the world of weather forecasting—specifically the apps on our phones that we have come to rely on. As climate change intensifies storms and smartphones put hyperlocal forecasts in our pockets, we’ve never had more meteorological data. And yet plenty of people lament that their weather apps can’t get it right. Charlie digs into why we obsessively refresh our weather apps, why we blame them when they’re wrong, and what it really means to forecast an inherently chaotic atmosphere. Charlie talks with the physicist Adam Grossman, a co-creator of the cult-favorite weather app Dark Sky that redefined minute-by-minute forecasting before being acquired by Apple. Grossman pulls back the curtain on how weather predictions are made—a process that includes satellites, weather balloons, massive physics simulations, and machine-learning models—and explains why forecasts are improving even if it doesn’t always feel that way Get more from your favorite Atlantic voices when you subscribe.

Few companies have reshaped American culture as aggressively as Netflix. This week’s Galaxy Brain charts how we got here. Charlie Warzel talks with Atlantic film critic David Sims about Netflix’s strange, sweeping arc: from red DVD envelopes to a streaming colossus with 325 million subscribers. Sims explains how Hollywood initially shrugged off streaming as a novelty, only to watch Netflix reshape both distribution and the aesthetics and economics of entertainment itself.  Together, they discuss the rise of binge culture, data-driven green-lighting, and the tension between prestige projects and “second screen” slop built for distracted viewers. The conversation also examines Netflix’s stance toward theaters, its aborted bid for Warner Bros. Discovery, and the deeper question haunting the industry: Has Netflix simply exploited technological inevitabilities—or has it rewired our expectations of what movies and television are supposed to be?

Silicon Valley runs on hype cycles, and the AI boom is generating a new one—part gold rush, part ideology, and part quasi-religious devotion to building an alien intelligence. On this week’s “Galaxy Brain,” Charlie Warzel explores the culture of this boom with the writer Jasmine Sun, who’s been chronicling San Francisco’s AI scene. Sun describes what this moment feels like on the ground, including a subculture of massive salaries, and a weird pride in leaning into tech’s strangeness. Together, Warzel and Sun unpack two major factions shaping the industry: the AI “doomers,” and the accelerationists. The conversation also traces Silicon Valley’s rightward drift—the “founder mode” backlash against regulation and employee activism and the rise of “Trump style” provocation-first tech marketing. Finally, Sun and Warzel address the jagged reality of today’s models, which are brilliant at some tasks and weak at others.  Get more from your favorite Atlantic voices when you subscribe.

Silicon Valley relies on hype cycles. But for the last few weeks, AI insiders have been spooked by advances coming from their tools. On this week’s Galaxy Brain, Charlie Warzel helps listeners calibrate their anxiety about AI’s next phase. The episode examines what’s new: AI-agent coding tools that can work in the background like personal assistants. Warzel is joined by longtime technologist Anil Dash to unpack how hype and venture-capital incentives can distort the conversation around advances, and what the rise of tools like Claude Code and the more reckless “OpenClaw” experiments mean for labor, security, and everyday work. Dash outlines the very real risks of AI to explain why some people are panicking, why others are quietly building alternatives, and what to watch for as AI moves beyond chatbots to autonomous agents.

On this week’s Galaxy Brain, host Charlie Warzel dives into the state of the music industry, where streaming economics, algorithmic discovery, and generative AI are reshaping how music is distributed as well as what it means to make music in this environment. The episode traces how playlists and opaque recommendation systems have left many artists feeling like they’re battling an algorithm. With AI-generated songs now flooding platforms, and even in one case landing on a Billboard chart, the episode examines how automation, impersonation, and synthetic “diet music” are crowding into a system already strained by low payouts and creative burnout. Charlie is joined by Stu Mackenzie, the front man of the prolific Australian band King Gizzard & the Lizard Wizard, to talk about making music in the algorithmic age. From embracing bootleggers to pulling its catalog from Spotify, Mackenzie explains how the band has tried to protect its creative core while the industry transforms around it. Charlie and Stu explore whether we’re witnessing a normal technological shift or something more existential—an era where music is treated as pure commodity.

On this week’s “Galaxy Brain,” Charlie Warzel takes listeners deep into the internet’s fever swamps to examine how figures who once would’ve stayed on the fringes now dominate mainstream feeds. The episode charts the rise of Clavicular, a young livestreamer who’s gone from an absurdist curiosity to a fixture in the manosphere and its adjacent right-wing influencer culture. Using Clavicular as a lens—his extreme body modification, relentless self-documentation, and a willingness to do anything for attention—Charlie discusses the rise of nihilistic Zoomer influencers. Then he’s joined by the internet-culture researcher Aidan Walker, who helps situate Clavicular alongside figures such as Nick Fuentes and Andrew Tate, revealing how the “looksmaxxing” movement collides with grievance politics and an anti-political, “algorithm-first” ideology. Together they explore what happens when the gatekeepers are gone, and when nihilism becomes a default way for budding attention hijackers to build an audience.

On this week’s Galaxy Brain, Charlie Warzel opens with what it means to live in 2026, when our phones can drop us into graphic, real-time violence without warning—and when documenting that violence can be both traumatizing and politically consequential. Using recent footage out of Minneapolis as a lens, he explores the uneasy collision of algorithmic feeds, misinformation, and the moral weight of witnessing. Charlie also traces how viral documentation can puncture official narratives, pushing stories beyond political circles and into unexpectedly “apolitical” corners of the internet, even as platform-ownership shifts and suspected censorship (or outages that look like censorship) deepen public paranoia about who controls what we see. Then, Charlie is joined by Amanda Litman, a political digital strategist and the co-founder of Run for Something. They discuss how to be a good citizen in the information war without losing your mind. Specifically: In an age of algorithmic fragmentation and billionaire-owned platforms, does sharing that devastating image or news article actually accomplish anything? Or is it just performative activism? Together they explore how nonpolitical creators and everyday people can be especially persuasive messengers, and how to pair online engagement with offline activism. It’s an episode about how to stay engaged without surrendering your nervous system and how to use the internet as a tool for connection, clarity, and action, not just despair.

In this episode of Galaxy Brain, host Charlie Warzel speaks with the reporter Ryan Broderick about how the internet’s fragmentation of attention and facts has bled into real-world political violence in Minneapolis this month. From the viral spread of a right-wing video about day-care fraud in Minnesota to the aggressive ICE activity in the region that followed, the episode charts how online content routinely shapes government action and public perception. Broderick, who spent days in Minneapolis after the shooting of Renee Nicole Good, describes what he saw on the ground: how protesters and law enforcement are behaving differently this time around, especially with regard to filming and digital organizing. The conversation explores a novel and concerning feedback loop where what happens online spurs real-world interventions, which then generate more content for audiences elsewhere, compounding division and uncertainty about what’s true.  Get more from your favorite Atlantic voices when you subscribe.

In this episode of Galaxy Brain, Charlie Warzel confronts the growing crisis around AI-generated sexual abuse and the culture of impunity enabling it. He examines how Elon Musk’s chatbot Grok is being used to create and circulate nonconsensual sexualized images, often targeting women. Warzel lays out why this moment represents a red line for the internet: It is a test of whether society will tolerate tools that silence women through humiliation and intimidation under the guise of free speech. Warzel is then joined by The Atlantic’s Sophie Gilbert, the author of Girl on Girl, for a conversation about how misogyny has been a constant throughline in the history of internet innovation, from Facebook to YouTube. Warzel and Gilbert discuss today’s AI-powered exploitation and explore how new technologies repeatedly repackage old abuses at greater scale and speed. They discuss why this wave of hostility feels so intense right now, how backlash politics and platform design reinforce one another, and what is at stake if lawmakers, companies, and the public fail to draw a red line with Elon Musk’s Grok.

In this episode of “Galaxy Brain,” Charlie Warzel discusses the nightmare playing out on Elon Musk’s X: Grok, the platform’s embedded AI chatbot, is being used to generate and spread nonconsensual sexualized images—often through “undressing” prompts that turn harassment into a viral game. Warzel describes how what once lived on the internet’s fringes has been supercharged by X’s distribution machine. He explains how the silence and lack of urgency isn’t just another content-moderation failure; it’s a breakdown of basic human decency, a moment that signals what happens when platforms choose chaos over stewardship. Then Charlie is joined by Mike Masnick, Alex Komoroske, and Zoe Weinberg to discuss a vision for a positive future of the internet. The trio helped write the “Resonant Computing Manifesto,” a framework for building technology that leaves people feeling nourished rather than hollow. They discuss how to combat engagement-maximizing products that hijack attention, erode agency, and creep people out through surveillance and manipulation. The conversation is both a diagnosis and a call to action: Stop only defending against the worst futures, and start articulating, designing, and demanding the kinds of digital spaces that make us more human.
