Most Replayed Moment: Stanford's AI Economist Names the Jobs That Won't Exist in 5 Years | Erik Brynjolfsson

Erik Brynjolfsson, an economist at Stanford who has spent decades studying how technology reshapes labor markets, offers a direct assessment: junior software engineers, mid-level marketing managers, and paralegals are jobs whose core functions are already being automated. But the full picture is more complicated than a simple list of disappearing roles. Brynjolfsson argues that the real transformation is not about which jobs vanish, but about how the structure of work itself is being reconfigured—and that most companies are not prepared for what is coming.

The New Structure of Work: From Pyramid to Diamond

Brynjolfsson describes a fundamental shift in how work gets done. Historically, most jobs involved three phases: defining the question, executing the solution, and evaluating whether the result was correct. AI agents, he explains, are becoming extremely good at the middle phase—execution. "Once you ask the right question, these tools will execute and generate software," he says. This means that in the near future, most knowledge workers will function like "the CEO of a bunch of agents," focusing their energy on the first and third phases: asking the right questions and evaluating the output.
