Joseph Stiglitz wants you to hold two ideas in your head at the same time. The first: an AI bubble is building, it will likely burst, it will hurt the macroeconomy, and workers will bear the cost of a displacement we have no institutions to manage. The second: survive that transition, and the technology that threatens your job today may end up becoming your most useful co-worker.<\/p>\n
\u201cOur economy is right now being supported by AI investment\u2014the AI bubble,\u201d Stiglitz told Fortune in a recent interview. \u201cLike a third of the growth, or the non-growth, that we had last year was based on AI. So this AI bubble is having positive macroeconomic effects in the short run. I believe that it is a bubble in two ways.\u201d<\/p>\n
\u201cThere\u2019s both a short run and a long run,\u201d he said. The problem, Stiglitz argued, is that almost everyone in the public debate is only hearing one of them.<\/p>\n
If there\u2019s a bubble, it will have an explosive burst<\/p>\n
Stiglitz, who won the Nobel Prize in economics and wrote about the structural failures of modern capitalism in his 2024 book The Road to Freedom: Economics and the Good Society, believes the current wave of AI investment rests on a foundation that cannot hold.\u00a0<\/p>\n
\u201cThe market believes that there are going to be high returns to these investments that is predicated on two assumptions: that AI will be technologically successful and that there will be limited competition,\u201d he said.\u00a0<\/p>\n
The problem is that global competition in AI is already fierce, from U.S. tech giants to Chinese firms. \u201cBecause if it\u2019s technologically successful, but there\u2019s a lot of competition, profits will be driven down to zero, and they will not get the returns that they expect.\u201d<\/p>\n
When that realization hits, the fallout will not be gentle. \u201cIf I\u2019m right and there is this bubble,\u201d Stiglitz warned, \u201cthen the breaking of any bubble is really bad in the short term for the macroeconomy.\u201d<\/p>\n
That collapse, if it comes, would arrive while AI is simultaneously displacing workers across the economy\u2014a worst-of-both-worlds scenario that Stiglitz does not think is far-fetched.<\/p>\n
\u201cWe do not have the macro or micro framework for managing that kind of displacement,\u201d he said. No active labor-market policies. No large-scale retraining infrastructure. No industrial strategy to create the next round of good jobs in the places where old ones are disappearing. \u201cIt would require large retraining programs and so forth\u201d\u2014programs that do not currently exist at anything close to the scale needed.<\/p>\n
The displacement gap<\/p>\n
Stiglitz has seen what happens when societies lack those tools.<\/p>\n
\u201cWhen in the Great Depression, it was partly a success of agriculture,\u201d he said. \u201cWe increased productivity enormously. We didn\u2019t need as many farmers, but we had no ability to move people out of the rural sector\u2014and we finally did it in World War II. But it was government intervention as a result of the war that resolved that problem. We don\u2019t have the institutional framework for doing that.\u201d<\/p>\n
The parallel is not comforting. If AI succeeds at automating large portions of routine cognitive work\u2014the research, the drafting, the analysis, the administrative processing that fills millions of office jobs\u2014and the economy has no mechanism to redirect that labor, the result is not just a productivity story. It is a human one. \u201cThe foundations of a strong macroeconomy are almost inconsistent,\u201d Stiglitz said. \u201cI just can\u2019t see how it can happen.\u201d<\/p>\n
He\u2019s clear that AI will \u201cmake a particularly large difference in some of the routine white collar jobs\u201d\u2014the very jobs that tend to sit behind desks, carry college degrees, and feel furthest from the disruptions that hammered manufacturing workers a generation ago. The sense of safety many knowledge workers feel may be exactly backwards.<\/p>\n
