Robert Solow, an economist, said in 1987 that computers show up everywhere except for the productivity statistics. It took a good two decades at the time for this to fundamentally change.
I predict the same “Solow Paradox” will apply to AI and its newest incarnation LLMs (of which GPT is a variant). Over the next few years a lot will happen in terms of adoption that will not show up positively in productivity statistics (in some cases it will actually show up negatively… 😉).
The difference will be that gains will start to show up at the end of a single decade of adoption instead of two.
