This post originally began as a reaction or riff on a post I saw at Substack but which I’ve lost track of. I wanted to make several points about the artificial intelligence craze that is presently under way.
My first is that, yes, we are in an artificial intelligence mania, rather similar to the Tulip Mania of the 17th century. Microsoft, Alphabet, Meta, and Amazon spent hundreds of billions of dollars on generative AI (GAI) in 2024. That certainly qualifies as a “mania”.
And it’s just getting started. You can reckon the beginning of the bubble from the launch of ChatGPT in 2022. Based on previous experience with bubbles, they typically last around five years. Like previous bubbles this one is propelled more by “fear of missing out” (FOMO) than it is by actual benefits.
It’s interesting to consider the changes wrought by the last major technological shift, the shift to mobile devices. When it began with the introduction of the iPhone, the largest companies in the S&P 500 were (in descending order) ExxonMobil, General Electric, Microsoft, Citigroup, and AT&T. By the launch of ChatGPT they were Apple, Microsoft, Alphabet, Amazon, and Berkshire Hathaway. At five times the market capitalization of their predecessors. Don’t be surprised if the leaders have changed just as much by 2030. Hence, FOMO.
Just as the infrastructure investments of the iPhone revolution were borne by telecommunications companies but other companies realized most of the benefits, again don’t be surprised if the same thing happens with the implementation of GAI.
One of the ways in which GAI will provide different improvements in automation from those of the 20th century is that rather than reducing the number of unskilled workers required for tasks it will provide the opportunity to increase the productivity of skilled activities that rely heavily on memory and adhering to certain guidelines.
The big question will be who captures the economic surplus realized from such efficiencies? Capital? Skilled workers? Consumers? Considering the entrenched interests and their power, I anticipate an enormous political battle over who benefits.
A final intriguing aspect of this shift is that it will go on primarily in the United States for political, social, and economic reasons. The U. S. is already very different from our European cousins in important ways (there are no trillion dollar European companies) and I suspect this shift will make the differences even more pronounced.
