I've got an article about this exact dynamic in my drafts! Should definitely throw in this example.
WRT technology changes, people see direct costs that will go down, and often make predictions that treat that visible change like that's the only cost category affected. You can see it most cleanly in articles about what the Internet -> crypto -> AI will do to transaction costs.
The problem is treating "transaction costs" as one number and start treating it as a profile of categories. Dating apps torpedoed search costs but inflated screening, measurement, and cognitive costs, and made switching costs low enough to introduce perverse incentives.
Matchmakers aren't exactly what they used to be, and search cost reduction is no longer their biggest value-add (though they take advantage of Internet's reduced search costs). They now sell screening/evaluation and cognitive cost reduction and much better principal-agent alignment. Net market is bigger, people get better matches, but the overall market structure is very different.
Many similar patterns apply wrt AI/Jobs, but also AI shifts a much broader set of costs, and AI sits on both sides of the dynamic (and on both sides of most cost shifts) -- it creates new credence goods to be screened/evaluated *and* does screening/evaluation. It adds cognitive load *and* reduces it. Dating is symmetric between two principals, and matchmaking adds an agent in-between, while employment is asymmetric and principal-agent. Some of AI's cost-shifting will increase demand for things humans are particularly good at, but they'll also increase demand for AI in many of the same areas.
