Radio Atlantic – “What If AI Is a Bubble?”
Podcast: Radio Atlantic
Host: Hanna Rosin
Guest: Charlie Warzel (Tech Writer, The Atlantic)
Date: November 13, 2025
Episode Overview
In this episode, Radio Atlantic probes the provocative question: Is the AI boom actually a bubble—and if so, what would happen if it burst? Host Hanna Rosin and tech journalist Charlie Warzel unpack the vast sums of money pouring into AI, the structural changes underpinning its proliferation, and the uneasy parallels with past economic bubbles. Through data, reporting, and candid reflection, they dissect the hype, the risk, and the tangible consequences for the broader economy and society if AI can’t deliver on its immense promise.
Key Discussion Points & Insights
1. Unprecedented Investment in AI
- Enormous Sums: Huge, almost incomprehensible amounts are being poured into AI. Nvidia—a linchpin in the AI chip market—recently surpassed a $5 trillion valuation.
- Quote [00:35] Hanna Rosin: “The amount of money invested in AI these days is astonishing, almost unfathomable. Like you might even need AI to truly comprehend it.”
- AI Stocks Dominate: The “Magnificent Seven” tech companies (Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia, Tesla) make up more than a third of the S&P 500.
- Investment Scale: Global AI spending is projected at $375 billion for 2025, rising to nearly $500 billion in 2026.
- Quote [01:29] Charlie Warzel: “Global spending is projected to surpass or hit 375 billion this year. And in 2026, the figure is supposed to go up to close to a half a trillion dollars.”
2. Discrepancy Between Investment and Profits
- Revenue Lagging: Despite astronomical investment, AI hasn’t yet delivered profits or dramatically improved productivity at scale.
- Quote [02:21] Sam Altman: “The honest answer is we have no idea. We have never made any revenue. We have no current plans to make revenue… once we’ve built this sort of generally intelligent system, basically we will ask it to figure out a way to generate an investment return for you.”
- Everyday Investors Are Exposed: Whether you realize it or not, if you’re invested in index funds, you are exposed to the AI sector.
- Quote [04:21] Charlie Warzel: “These are stocks that are not only a big part of the S&P 500, but they're also where a lot of retail investors are put in…even if you are not thinking that you are investing in the AI boom…you are in this boom in some way.”
3. Is the AI Boom a Bubble?
- Hype vs. Reality: There’s mounting anxiety about whether current investments are justified.
- AI’s Real Impact So Far: A McKinsey report found that 80% of surveyed companies saw no "significant impact" from AI on their bottom lines.
- Quote [05:59] Charlie Warzel: “80% of the companies they surveyed that were using AI discovered that the technology had no real, they said, significant impact on their bottom line… these tools are not yet, at least as they exist now, as transformative, as people are saying…”
4. Structural and Infrastructural Challenges
- Data Centers and Energy: The AI boom is as much about physical infrastructure—costly data centers, electricity, and land—as it is about software or algorithms.
- Quote [06:33] Charlie Warzel: “…we need to blanket the Earth in these data centers in order to make this go.”
5. Bubble Parallels with the Dot-Com Era
-
Historical Echoes: Current hype resembles the 1990s dot-com bubble, where vast investment far outpaced what the tech could deliver.
- Quote [08:44] Charlie Warzel: "The dynamic of the dot com crash wasn't that the Internet was a fad. It was that all this investment came in and all these companies were created and the ecosystem wasn’t yet developed enough to support it."
-
Revenue vs. Spend: To break even on data center investments alone, AI companies would need to generate between $160–$480 billion in revenue—a figure wildly out of sync with current capability.
- Quote [10:05] Charlie Warzel: “…the revenue that these tech companies would need to generate to break even on this year's capital expenditure alone is closer to $320 or $480 billion.”
6. “Magical Thinking” and FOMO on Wall Street
- Future-Proofing: Much of the investment is predicated on the promise—or “magical thinking”—of “superintelligence” that's supposedly just over the horizon.
- Quote [12:34] Hanna Rosin: “We'll just build a super intelligence and then ask it to solve this math problem for us.”
- No Brakes on Spending: Wall Street isn’t tapping the brakes. There’s tremendous FOMO (“fear of missing out”) and a sense of geopolitical urgency, especially vis-à-vis China.
- Quote [12:39] Charlie Warzel: “…there is just no one is blinking when it comes to the money that's being invested. Like the lights are all green here…There's this FOMO that is happening right now.”
7. The Industry’s Arguments Against the Bubble Narrative
- Public Exposure as a ‘Check’: So many eyes are watching “the bubble” that its excesses are supposedly self-limiting.
- Quote [15:54] Charlie Warzel: "Everyone says we're in a bubble and everyone's watching it…how can it get so out of hand? This is happening sort of in public."
- Physical Constraints: Real-world limits—on chips, land, labor—may force slower, more realistic scaling.
8. Complex Financial Engineering—Risk of Systemic Contagion?
- Data Center Financing: Tech firms are partnering with private equity to finance data centers via rent schemes, with those obligations bundled into financial instruments—a process reminiscent (but not identical) to the 2008 mortgage crisis.
- Quote [16:26] Charlie Warzel: "They're combining that with others into these securities that are based off of tranches…that are based off of how risky they are in terms of default. And if any of those words sound familiar…that's a little bit similar to some of the financial engineering of the 2008 crisis, right? With subprime mortgages."
- Transparency Risks: The complexity and opacity of these deals makes the scale and risk of investment harder to track—and may enable hidden vulnerabilities.
9. Lose-Lose Scenarios and “Too Big to Fail” Questions
-
Between a Rock and a Hard Place: If AI fails to deliver, massive economic pain could ensue as the bubble bursts. If it succeeds, we could face unprecedented economic disruption and mass unemployment.
- Quote [22:13] Hanna Rosin: “It sounds like you're saying it's chaos either way. Like there's a bubble that brings pain…or a true breakthrough that brings disruption and possibly mass unemployment.”
- Quote [22:28] Charlie Warzel: “If these companies create the thing that is worthy of this much investment, it is going to cause an extreme amount of societal rewiring and probably financial pain. And if they don't manage to pull it off, I think it's going to cause an extreme amount of financial pain, so.”
-
Too Big to Fail?: The government may view AI sector stability as a geopolitical imperative, raising the specter of bailouts, should disaster strike.
- Quote [23:03] Charlie Warzel: “There is a really interesting, I guess, debate…around the notion of will these companies be put in a too big to fail bucket?”

Conclusion: Where Do We Go From Here?
The episode closes on a sobering note, suggesting a future of instability or disruption no matter how the AI boom plays out. The immense investment in AI is either setting us up for unparalleled creative destruction or for a crash with wide economic repercussions. Further complicating matters, the scale of investment, the intertwining with American retirement funds, and the possibility of government backstops mean the consequences could be systemically important, whichever way the gamble falls.
For listeners wanting clarity on the AI investment craze’s reality versus its mythos, this episode offers a nuanced, constructive skepticism—without easy answers, but with a sharp eye on the potential for both innovation and trouble.
