New Substack post with @soumitrashukla9. Work has never been just about the income earned sans effort costs, as typical in economic models. Key aspects of people’s identity, their meaning, and sense of agency are all wrapped up with what they do for a living. There has been a lot of conversation lately about how technological change, particularly AI, may disrupt this relationship, from Ezra Klein's column on his own mathematician father’s grapplings with losing meaning in mathematics, to Francis Fukuyama's post on AI, agency, and recognition. In this piece we take a historical perspective on how technological transformation has disrupted identity and meaning by affecting jobs, and how workers and society responded to these changes. Much of the debate around AI and jobs has centered on wages and material consequences, but losing one's work is also intertwined with how people view their place in society. Most people know about the Luddites—skilled weavers and knitters—who protested the devaluation of their mastery. What’s less known is that the Luddites were actually experts in using the machines as well, and that their protests prompted prominent economists like David Ricardo to rethink the role of automation in society, and later inspired the Arts and Crafts movement. A century later, when recorded sound displaced 20,000 cinema musicians, their campaign against "canned music" and two-year recording ban pressured labels into funding live performance. Soumitra and I have been working on versions of this essay for months. He led the piece, and we’re both really excited to get it out there. Link to the post here: aleximas.substack.com/p/tech…
The most revealing part of this conversation between Jon Stewart and Jacob Coxon wasn't Coxon's warning about A.I. doom, but his description of A.I. utopia, and Stewart's incredulous response. I wrote about it — and Francis Fukuyama's "Last Man," and A.I. easily solving the problems that bedeviled my father's field of mathematics for decades — here: nytimes.com/2026/10/18/opini…

The university of the future will consist of just two things: admin and AI.
How bad is administrative bloat in higher ed? At MIT, the “student body has grown by 8% and its faculty by 9% since the mid-1980s. By comparison, the tally of administrators jumped by 189%.”

Politeness in China is on the rise. Giving a lecture in China, I made a mathematics mistake on the board. A student raised his hand and said, “In China, we do it differently.”

I can assure you that being an academic in 2026 is nothing like being a miner in 1982.
One professor who recently left academia said it felt like being a miner in 1982 and it’s hard to disagree

Thor Berger @bergerthor has written a great paper on the effects of the diffusion of tractors in the United States, with a very nice thread that describes the analysis. The widespread adoption of tractors led to increased human capital investment both because children of farmers left agriculture. On the other hand, those areas that adapted most quickly exhibited the largest graduation effects, suggesting human capital investment was able to generate complementaries between farmers and tractors as the technology of agricultural production evolved. This possibility, of course, has contemporary resonance.

In honour of Thor's new working paper: a photo of me and my tractor. There are few more important topics in life, let alone in economic history.

Yes! And the introduction of agricultural education in the HS curricula spurred enrollment among farm boys because they perceived it “dealt with the realities of life, with real problems instead of imaginary ones".
Replying to @bergerthor
Did the high schools change their curricula and hiring practices to become more attractive to these boys who might now seek their high school diploma?

A great historical example of positive labor market response to a big automation shock: Tractors automated farm labor; teen boys stayed in school longer. Adjustment on the margin of labor market entrants = much less costly
Replying to @bergerthor
Enrollment tells the same story: as tractors spread, enrollment rises sharply among farm boys of high-school age, but not at younger ages or among nonfarm boys. (8/14)

Takeaway: Automation shapes the next generation’s investment in education, partly because it helps them adapt and persist in sectors undergoing rapid technological change.
