Google CEO Sundar Pichai has issued a stark warning: No tech company, including his own, would escape unscathed if the artificial intelligence (AI) investment bubble were to burst.

In an interview with the BBC conducted at Google’s Mountain View, Calif., headquarters, Pichai acknowledged “elements of irrationality” in the current AI market, drawing uncomfortable parallels to the “irrational exuberance” that preceded the dot-com crash of 2000.

“I think no company is going to be immune, including us,” Pichai said when asked whether Google could weather a potential AI market correction. His candid admission comes as mounting concerns about soaring valuations and heavy investment in the sector fuel fears of a repeat of the late 1990s internet boom and bust. (More than $5 trillion will be invested in data centers and AI infrastructure worldwide over the next five years, according to JPMorgan Chase.)

The warning follows similar cautionary notes from JPMorgan Chase CEO Jamie Dimon, who told the BBC last month that while AI investment would ultimately pay off, some of the money being poured into the industry would “probably be lost.”

The stakes are enormous. Alphabet’s shares have surged 46% this year, with the company’s market value doubling to $3.5 trillion in just seven months as investors bet on its ability to compete with OpenAI.

At the same time, analysts are anxious about a complex web of $1.4 trillion in deals surrounding OpenAI, which is expected to generate revenue this year of less than one-thousandth of the planned investment.

Despite bubble concerns, Pichai argued that the current wave of AI investment represents an “extraordinary moment” and insisted Google was better positioned than most to survive any market turbulence. He highlighted the company’s ownership of a “full stack” of technologies — from specialized AI superchips that compete with NVIDIA Corp. to YouTube data, models, and frontier science research.

“We can look back at the internet right now. There was clearly a lot of excess investment, but none of us would question whether the internet was profound,” Pichai told the BBC. “I expect AI to be the same. So I think it’s both rational and there are elements of irrationality through a moment like this.”

Pichai also announced Google would begin training AI models in Britain for the first time, a move Prime Minister Keir Starmer hopes will cement the UK’s position as the world’s third AI “superpower” after the United States and China. The announcement builds on Alphabet’s September pledge to invest $6.6 billion over two years in UK AI infrastructure and research, including developing “state of the art” research at its London-based DeepMind unit.

However, Pichai warned AI’s “immense” energy demands — which accounted for 1.5% of global electricity consumption last year, according to the International Energy Agency — would force delays in Alphabet’s net-zero climate targets. While the company maintains its 2030 net-zero goal, “the rate at which we were hoping to make progress will be impacted,” he acknowledged.

Looking ahead, Pichai described AI as “the most profound technology” humanity had developed, predicting significant workplace disruption alongside new opportunities. “It will evolve and transition certain jobs, and people will need to adapt,” he said, adding that those who learn to use AI tools effectively “will do better” across all professions, from teaching to medicine.

“The panic that we’re currently seeing is a classic mid-cycle wobble. Demand is still going parabolic, and cloud providers can’t expand capacity fast enough to meet it. This is simply not how bubbles burst – they burst when supply outweighs demand, leverage soars, or liquidity gets tight. This isn’t what we’re seeing right now,” Nic Puckrin, investment analyst and co-founder of The Coin Bureau, said in an email. “A correction at this point is expected and healthy, but it’s not the end of the road. This middle phase – where infrastructure buildout is still trying to catch up with demand – can easily last 12 months or more before things overheat.”
