Over the last few months, I’ve been trying to answer one deceptively simple question: how much revenue does the AI industry actually need to justify the hundreds of billions of dollars it’s pouring into new data centers and infrastructure?

The more I dug into it — and the more I spoke with those building, financing, and operating these facilities — the clearer the answer became: far more than anyone is willing to admit.

And yet, as Jeff Bezos reminded a room full of entrepreneurs recently, technological progress has always looked this way in its early stages: messy, excessive, often irrational — and, if history is any guide, deeply productive in the long run.

The Arithmetic of Excess

The numbers themselves are startling. The AI industry is now spending close to $30 billion every month — roughly $400 billion a year — building datacenters, racking GPUs, and expanding power capacity. Annualized revenue from AI workloads, however, remains around $15 billion–$20 billion.

At first glance, this might seem manageable — until you adjust for the brutal depreciation cycle. These facilities aren’t 10-year assets. They’re three- to five-year consumables. New chip generations, new cooling architectures, and new rack designs make today’s capital obsolete before it’s paid off.

Once you factor that in, the break-even revenue to justify 2025’s spending jumps to $320 billion–$480 billion. Add another year of construction and the number swells to $1 trillion. The gap between ambition and monetization is extraordinary — and it’s widening.

Why the Flywheel Keeps Spinning

If the math doesn’t make sense, why hasn’t the machine stopped? Because incentives haven’t changed. Hyperscalers can absorb losses, investors continue to reward growth, and governments see AI as a matter of strategic necessity.

This is precisely the kind of environment Bezos calls an industrial bubble: when everything — good ideas, bad ideas, crazy ideas — gets funded, and both signal and noise rise together. Investors lose discrimination, valuations detach from fundamentals, and yet society ends up wealthier for it.

It happened with fiber-optic cables in the 1990s — most companies failed, but those “excess” cables became the backbone of the modern internet. It happened in biotech, where hundreds of startups went under but left behind a handful of life-saving drugs.

AI, Bezos argues, will follow the same pattern: 90 percent of companies will disappear, but the remaining 10 percent — and the infrastructure they leave behind — will transform the economy.

The Historical Echo

That paradox — overbuilt today, indispensable tomorrow — is woven into the fabric of progress. Railroads bankrupted investors but built nations. The fiber boom collapsed valuations but seeded two decades of digital expansion.

Bezos calls this dynamic “civilization advancing through over-investment”: someone always builds more capacity than the moment requires, and that surplus becomes the foundation for something extraordinary.

But here’s the caveat. Not all bubbles are created equal. A financial bubble — like the 2008 credit crisis — is destructive, leaving behind only debt and fragility. An industrial bubble, by contrast, leaves behind tools, platforms, and knowledge. The question for investors is not whether AI is a bubble. It is what kind of bubble it will become.

The Macro Fragility Beneath the Hype

The stakes extend far beyond corporate earnings. Once you include associated power projects, supply chains, and ancillary R&D, AI investment now accounts for roughly 1.5 – 2 percent of U.S. GDP. Remove it, and the economy would likely flirt with recession.

There’s also the wealth effect. Roughly half of U.S. consumption comes from the top decile of households, and their spending is closely tied to equity performance. Because most of this year’s stock-market gains have been concentrated in AI-linked names, any correction could reverberate through consumer demand.

The paradox is stark: the same boom that’s propping up growth could, if it reverses, expose how dependent the U.S. economy has quietly become on this single narrative.

The Counterweight: Structural Strength

There is, however, a crucial difference between today and 2000. The core players — Microsoft, Meta, Amazon, and Google — are fundamentally stronger than the dot-com darlings ever were. They generate vast free cash flow, carry virtually no leverage, and enjoy deep moats in enterprise software, cloud, advertising, and ecosystems. Their valuations are rich, but not absurd.

That means the eventual correction — and one will come — is likely to be more measured. It may reset expectations, crush marginal players, and reprice suppliers, but it is unlikely to collapse the ecosystem.

The real risk lies in excess liquidity. If a Federal Reserve pivot fuels speculative mania on top of already-aggressive spending, the aftermath will be harder and longer. Easy money has a way of turning productive bubbles into destructive ones.

The Long Game: Optimism With Eyes Wide Open

Bezos often says that long-term thinking is not just a strategy — it’s an ethical framework. It forces you to build for decades, not quarters; to prioritize trust over transactions; and to anchor yourself in the things that don’t change.

That mindset matters now more than ever. If you zoom out, the slope of human progress is almost always positive. Overinvestment, inefficiency, even speculative froth — they’re all part of the creative process. “Reality always wins,” Bezos reminds us — and reality is that AI is a horizontal capability that will eventually touch every industry, from logistics to healthcare, farming to finance.

The infrastructure being built today — even if overbuilt — will power that transformation.

Ten years from now, we may look back on the waste and misallocation with frustration, but we’ll also acknowledge that it paved the road to abundance.

Where This Leaves Us

So where does that leave investors and policymakers? Somewhere between caution and conviction.The short-term risks are real: distorted incentives, unsustainable spending, and economic fragility. But the long-term potential is immense: a productivity boom, a new industrial base, and a wave of innovation that could lift global living standards.

Our task is to navigate both truths at once — to invest with a clear eye on risk, but without losing faith in the compounding nature of human ingenuity. Overbuilding is not, in itself, a mistake. It’s how civilizations lay the groundwork for their next leap.

The challenge is to ensure that when the dust settles, we’ve traded speculation for something far more valuable: enduring progress.
