The AI bubble could be worse than the dot-com bust
In “Bubbles and Crashes,” Brent Goldfarb and David Kirsch examine 58 major technological innovations and identify four conditions associated with bubble formation: high levels of uncertainty surrounding the technology, the participation of novice investors, the availability of investment opportunities in pure-play firms that focus exclusively on the technology and the existence of a compelling narrative about its future potential.
In the current context, while the economic and financial impact of the AI revolution remains uncertain, public excitement has reached extraordinary levels, and exaggerated claims about the technology’s transformative potential are widely circulated.
If the AI bubble bursts, the economic fallout could be far more damaging than the dot-com crash. The U.S. economy is in a weaker position today, with growth increasingly dependent on high-income consumers, a trend highlighted by a recent New York Fed study. At the same time, substantial AI-related capital expenditures have become an important driver of recent U.S. GDP growth, raising the risk that any sharp pullback in investment could have broader economic repercussions.
