Valuation Guru Damodaran Dismisses 'AI Will Triple GDP' Hype: 40 Years of Data Show No Productivity Gain

NYU professor Aswath Damodaran, the world's leading valuation expert and an AI skeptic, pushed back on the 'AI will triple GDP' narrative.

His core argument: global real GDP growth over the past forty years has been lower than it was before the PC. Technologies claiming to boost productivity, he says, mostly redistributed wealth rather than making society genuinely richer.

The comment was amplified by longtime AI skeptic Gary Marcus, adding weight to the growing pushback against bullish AI macroeconomic forecasts.
