It's in a section called "Why I’m still not afraid for my career."

The implication here is software engineer jobs are still safe despite basically free labor/material being available to do said jobs because he thinks other people would prefer to pay experienced professionals to do it right at a significantly higher cost. My point is, I think most people will take the low-stakes gamble of having the cheap AI agent do it with self-supervision[0]. He's naive in thinking people are really going to care about artisanal software built by experienced professionals in the future.
