Mollick cites 3.6% US productivity growth as evidence of AI's economic impact

Ethan Mollick, a Wharton professor, posted on X that US productivity grew at a 3.6% annual rate last quarter, citing economist Erik Brynjolfsson's post reporting the figure.

Brynjolfsson says the rate is more than double the 1.5% average from 2007 to 2019 and supports his bet with Bob Gordon about productivity growth in the 2020s.

Mollick's post links the figure to AI's economic impact. The source reports the growth rate and Brynjolfsson's view of the bet, and does not establish what caused the increase.
