Could AI lift productivity enough to ease debt concerns?
Core argument: By the end of the 1995–2005 productivity surge, U.S. productivity stood about 12% above the trend implied by 1973–1995 growth, according to the author's plot of log productivity.
Here’s a view of the 1995-2005 boom, in which I show the natural log of productivity — so that a straight line corresponds to steady growth — and plot a continuation of the growth rate from 1973 to 1995 (the red line), so that you can see how actual growth compared. By the time the productivity surge tapered off, productivity was about 12% higher than the previous trend would have led you to expect it would be. Since A.I. is arguably an even more profound innovation than the technologies that drove the 1995-2005 boom, 15% isn’t at all unreasonable. If optimistic estimates of the boost from the technology are at all right, growth will be much higher than conventional estimates of the economy’s long-run sustainable growth rate, like those of the Federal Reserve, which put it at around 1.8% over the next decade. [If that’s the case] debt won’t be a big concern after all — especially because faster growth will boost revenue and reduce the budget deficit.
