Are you feeling a little underwhelmed by AI’s transformation of the economy? The so-called “fifth industrial revolution” is supposed to wipe out half or even all of white-collar work and yet adoption is kind of begrudging, even optional for many workers. For those who have started using it, it kind of feels like homework a lot of the time—it writes your emails for you, but it’s still wrong a lot of the time. Three and four decades ago, the computer revolution was similarly hyped, and yet for a lot of the time, it looked more like Pets.com than what turned into the iPhone.
That’s the angle taken by Goldman Sachs’ Elsie Peng, who looked closely at the productivity uptick from the computing revolution in a research note for the bank earlier this month. The last time something this big came along, she wrote, things actually got measurably worse before they got better—for four years, by her reckoning. Then they flatlined for another four. Only in year eight did gains from computing become statistically significant. The productivity boom everyone associates with the personal computer didn’t actually show up in the macro data until 15 years after the PC was commercialized.
