"Will AI replace software engineers?" mostly gets answered with hot takes. Here's what the 2026 primary data says, from payroll records, job postings, a randomized trial and the largest field study so far.
In Stanford's words: "We do not see widespread, economy-wide job displacement associated with AI."
Where did the extra output go? Into review. Time from PR to merge rose 49%, the share of PRs needing changes nearly doubled, and comments per PR rose 35%. Code got cheap. Confidence that the code is right did not.
The workflow shifted too. 90% of developers in JetBrains' 2026 survey (vendor data) use AI coding agents at least weekly. The skills that gained value are writing context files, writing specs before code, and agentic engineering: parallel agents, small reviewable changes, CI as the gate, and a human accountable for every merge.
At Anthropic, the junior share of technical hires fell from 27% to 9% (its own October 2026 report). Some economists argue interest rates and pandemic over-hiring explain more of the decline than AI does. The likeliest answer is both. Either way, if companies stop hiring juniors, they stop growing the seniors they'll need to supervise agents later.
