Nov 9, 2026 — Debate over whether the artificial intelligence industry has formed a bubble is heating up again. On one side, an analysis argues outright that "I'm Not Convinced the AI Bubble Exists." On the other, questions are being raised about Nvidia. At the same time, a World Economic Forum report highlights water constraints on data centers, adding a new angle for scrutiny of AI expansion's sustainability.
Bubble debate: both sides weigh in
An article titled "I'm Not Convinced the AI Bubble Exists" drew attention on Hacker News, scoring 29 points and 12 comments as of publication. Its core argument: the current investment boom in AI does not fit the typical profile of a bubble.
Meanwhile, a user on the V2EX forum shared a post titled "Will it be Jensen Huang's zipper that pops the AI bubble?" — suggesting that events involving Nvidia (whose CEO Jensen Huang is nicknamed "Lao Huang") could be the trigger for a bubble burst. Prominent AI commentator Gary Marcus also published a Substack column titled "The Huang Affair: What did they know and when did they know it?", raising questions about the Nvidia-related events, though his summary said only "None of this was on my bingo card" without elaborating.

Water constraints: 45% of data centers in high water-stress areas
TMT Post, citing the World Economic Forum report, estimated that about 45% of the world's data center facilities are located in high water-stress areas. That means the growth in computing demand driven by AI expansion could intensify water stress in those regions.
| Key figure | Value |
|---|---|
| Share of data centers in high water-stress areas | About 45% |
The report sounds an alarm for the sustainability of the AI industry, with data center water consumption emerging as a new concern after chip supply and energy use.
Reactions and what to watch
The debate over an AI bubble continues. Bulls say AI investment is backed by fundamentals, while skeptics focus on potential risks at leaders such as Nvidia. The water constraint adds an environmental dimension to the long-term expansion of AI infrastructure.
What to watch next: further disclosures about the Nvidia-related events, the specifics of the World Economic Forum report, and how data center operators respond to water stress.
