Economist Paul Krugman argues that the vast sums going into AI data centres could support far fewer jobs than the same investment elsewhere, putting pressure on workers’ wages. His new essay sets out a striking estimate, but it is a counterfactual argument, not a prediction that millions of people will become unemployed.

What happened
Krugman draws on an estimate for a representative 200-megawatt AI training campus: about $8.2 billion to build, and roughly 50 to 150 workers once it is running. He contrasts that with an estimate that $8 billion invested elsewhere could support more than 10,000 jobs. Those figures underpin his argument that data-centre investment may crowd out more job-intensive uses of capital.
Krugman also cites a projection that hyperscalers will spend more than $10 trillion on data centres through 2032. Using his comparison, he estimates that this capital could employ roughly 10 million fewer workers than if invested elsewhere. Read Krugman’s essay.
Why it matters
The 10 million figure is not a forecast of people being made redundant or left unemployed. Krugman’s argument is that a shift in investment could reduce demand for labour compared with the alternative, putting downward pressure on wages and shifting more economic power towards capital. That is a consequential claim about who benefits from the AI build-out, not just how many chips it needs.
Our read
The useful question is not whether a data centre employs fewer people than a different kind of project. It is whether the investment really displaces other spending at the scale Krugman suggests, and what happens to workers as a result. The estimates make that debate concrete; the counterfactual deserves scrutiny before anyone treats its headline number as a jobs tally.
What to watch
- Whether the projected data-centre spending reaches the scale Krugman cites.
- How the underlying job estimates compare across industries and over time.
- Whether new evidence supports the claim that AI infrastructure is crowding out other investment.
Discussion spark: If AI data-centre investment creates fewer jobs than comparable spending elsewhere, should governments steer investment towards more job-intensive sectors, or accept the trade-off for AI’s potential gains?
