According to CoinMeta, the growth rate of labor productivity in the United States in the second quarter was faster than expected, with an annualized increase of 1.4%, higher than the revised 0.8% increase in the first quarter.

Federal Reserve officials, investors, and economists have been looking for signs to determine whether billions of dollars in investment in artificial intelligence are indeed boosting labor productivity. In the long run, improving productivity helps to enhance living standards, but some economists worry that if the productivity gains brought about by AI continue, some companies may delay hiring or even cut staff.
