The great productivity boom of the 2020s isn’t over, but it’s having an interlude. And it could become a long one if President Donald Trump remains committed to protectionist policies that make the economy less efficient. Ultimately, artificial intelligence will help, but it may take a while.

For all the caveats about Thursday’s statistic (the quarter-to-quarter data is notoriously noisy), it’s sure to burst the bubbles of fellow productivity bulls, who hoped it could sustain economic growth even as reduced immigration slows the expansion of the labor force.
