Concrete Evidence (October 26, 2026)
Everyone is worried about AI taking over jobs. Each week I’m deluged with papers trying to measure how “exposed” to AI competition each job is—and whether workers in these fields are suffering for it.
A new working paper from the Burning Glass Institute’s Soumitra Shukla flips this concept on its head—or at least on its side. Instead of focusing on which jobs might be displaced by artificial intelligence entirely, it asks which jobs contain an awkward mix of tasks—some of which can, but many of which cannot, be massively sped up with AI.
These are jobs that could change profoundly rather than disappear. In these jobs, workers’ efforts will likely narrow to focus on the tasks AI can’t do. Such tasks will become a “bottleneck” to productivity, and improving human performance in those areas will become especially valuable.
Using data from job postings on the tasks that different types of work involve, Shukla constructs an index of this “bottleneck pressure,” which reaches its maximum of 25 when a job is a perfectly even mix of AI and non-AI tasks, or 50 percent AI exposure.1
He also provides a handy list of how different jobs fare. For example, accountants face extremely high AI exposure, 90 percent, and thus have a low bottleneck score (8.7): AI is a big deal in this field, but there are few tasks that can’t be done that way to serve as bottlenecks. Fast-food cooks, with very low exposure (about 15 percent), similarly rate just a 13: humans aren’t bottlenecks when AI can’t do much work either way.
Occupations facing approximately the maximum pressure, thanks to roughly 50 percent AI exposure, include orthodontists and various types of technicians. This is where AI can do a lot, but only if humans keep pace with the other tasks.
Shukla also looks at the issue through the lens of the individual tasks rather than overall jobs. He highlights that the same tasks might serve as bottlenecks to different degrees in different fields.
Imagine that two different jobs involve the same task—a task that can’t be done with AI. However, one job is staying the same over time, while the other involves a lot of other tasks newly being done by AI. The task will be more of a bottleneck in the second job, and employers in that field might make special efforts to bring in employees good at the task.
For example, both fast-food workers and customer-service representatives need to greet customers and make them feel welcome. But the latter job’s other tasks are more exposed to AI, which could, over time, make human interaction a more important part of what’s left.
The paper is necessarily on the speculative side. You can empirically measure the tasks mentioned in job listings, but you can’t say for sure how AI will play out in each field and how jobs will evolve to accommodate it. Not all of the method’s job ratings made intuitive sense to me, either. Can AI really affect about 40 percent of the tasks required of a retail salesperson, which puts that occupation toward the high end of the bottleneck index?
Nonetheless, Shukla starts an important conversation here. It’s critical to understand what tasks AI can do and the jobs it might destroy—but maybe we should pay attention to the tasks it can’t do, and the jobs it can change, too.

From yours truly, a look at the future of antidiscrimination law’s “disparate impact” doctrine, which applies, for example, to hiring tests with uneven results across demographic groups. I focus on two threats to the doctrine in particular: the Trump administration’s efforts to address its constitutional issues, and the difficulty of applying its principles to new AI- and algorithm-based hiring technology.

Mathematically, the index is the exposure share times the unexposed share. So at 50 percent exposure we get 50 percent times 50 percent, or 25 on the index; and at 25 percent exposure we get 25 percent times 75 percent, or 18.75.
