Despite widespread corporate AI adoption with S&P 500 companies touting positive results, productivity gains remain elusive, echoing economist Robert Solow's 1987 productivity paradox with early computers. A recent study of 6,000 executives found minimal AI workplace impact despite two-thirds reporting usage. While executives forecast 1.4% productivity increases over three years, current data shows no measurable gains. Some economists suggest AI may follow a "J-curve" pattern similar to 1990s IT boom, with initial slowdowns followed by exponential growth, but timing remains uncertain.
