It does not show that AI has replaced software developers as an occupation.
Three outcomes the question merges
“Can AI replace developers?” bundles three different claims. Each needs different evidence, and the studies available speak to only some of them.

| Outcome | Question it answers | Evidence reviewed | What it does not settle |
|---|---|---|---|
| AI performs selected coding tasks | Can a tool complete a given task, and how fast? | METR’s controlled experiments (early-2025 study and 2026 follow-up estimates) | Whether a task-level result holds across all software work |
| The mix of developer work changes | Which activities take the time, and how teams use the time saved | DORA’s 2025 report; GitHub’s 2024 survey of tool use | Whether headcount falls |
| Aggregate demand for developers falls | Is employment in the occupation lower than it would otherwise be? | Federal Reserve discussion paper on coder employment (March 2026) | The share of any slowdown caused by AI, and the long-run net effect |
The title question is about the third row, while most of the measured evidence concerns the first two.
What the labor data shows
The most direct labor-market evidence is a March 2026 discussion paper by Federal Reserve staff, Leland D. Crane and Paul E. Soto. Linking O*NET occupation definitions to Current Population Survey data, they find a sharp deceleration in aggregate coder employment after ChatGPT’s introduction in late 2022. An industry-shock control suggests the slowdown is not explained by coders being concentrated in industries that were already slowing.
#1 Best Overall
The authors are equally clear that growth did not stop:
“Coder employment has continued to grow in recent years, though much more slowly than it did pre-2022.”
What the paper does and does not establish
- It establishes that coder employment grew more slowly after 2022 than before, and that the authors identify an occupation-specific shock around ChatGPT’s introduction.
- It does not establish that AI caused a specific number of job losses. It is a preliminary discussion paper, and its conclusions are the authors’ own views, not necessarily those of the Board of Governors of the Federal Reserve System.
- It does not show whether slower growth will continue, reverse, or accelerate.
What controlled productivity studies show
METR ran a controlled experiment in early 2025 with experienced open-source contributors. AI-assisted tasks took 19% longer to complete in that study. METR’s 2026 follow-up reports later estimates, summarized below.
| Estimate | Timing | Group studied | Raw result, as reported | Reported interval | METR’s caveat |
|---|---|---|---|---|---|
| Original experiment | Early 2025 | Experienced open-source contributors | 19% longer task completion with AI tools | 2% to 39% longer (interval level not stated) | Applies to this group; not a universal effect of AI coding tools |
| Follow-up estimate | Reported 2026 | Returning participants | 18% speedup | 38% speedup to 9% slowdown (95% interval) | Selection effects make it an unreliable proxy for real productivity impact |
| Follow-up estimate | Reported 2026 | Newly recruited developers | 4% speedup | 15% speedup to 9% slowdown (interval level not stated) | Same selection-effect caveat as the returning-participant estimate |
Why the 2026 follow-up cannot be read as a before-and-after result
The follow-up covered 57 developers across 143 repositories and more than 800 tasks. Participation itself changed once AI tools became part of the workflow. METR reports that some developers did not want to work without AI, that 30% to 50% said they withheld some tasks they did not want to do without AI, and that concurrent agents complicated time measurement. Those shifts make a simple early-versus-late comparison misleading. METR wrote in its February 2026 update:
“Due to the severity of these selection effects, we are working on changes to the design of our study.”
The defensible reading is narrow. Under early-2025 conditions, experienced open-source contributors took longer on the tasks studied when using AI tools. The 2026 figures are raw estimates whose intervals include both speedups and slowdowns, and they do not yet give a reliable productivity number.
Rank #4
Adoption is broad, but adoption is not intensity
GitHub’s 2024 survey found that more than 97% of 2,000 respondents had used AI coding tools at least once. The sample was non-student, non-manager enterprise respondents in the United States, Brazil, India, and Germany, 500 per country, at companies with at least 1,000 employees. Wakefield Research fielded the online survey from February 26 to March 18, 2024. GitHub published it on August 20, 2024 and updated the page on April 15, 2025.

The figure describes near-universal exposure in that sample at that time. It says nothing about how much code AI wrote, how much time it saved, or whether any role was displaced. Because the survey was sponsored by a vendor, read it as a measure of reported use rather than an independent census of developers. It also predates the METR studies above, so it describes 2024 tool use.
Why the same tool produces different results
The DORA 2025 report, from DORA at Google, draws on nearly 5,000 technology professionals worldwide and more than 100 hours of qualitative data. Its central conclusion is:
Best Value
“AI’s primary role in software development is that of an amplifier. It magnifies the strengths of high-performing organizations and the dysfunctions of struggling ones.”
In practice, the surrounding system determines what an individual’s faster coding turns into. Review capacity, delivery process, and team habits all sit between a quicker edit and a shipped product. This is DORA’s conclusion about organizations, not a settled law, and it is not a forecast of employment. Its value here is in explaining why studies of the same tools return different results.
Why productivity and headcount are different questions
Suppose a ten-person team completes the same backlog in 20% less developer time. This is a hypothetical, not a measured result. Several outcomes fit that number. The team could keep ten people and deliver more. It could hold output steady and hire more slowly as people leave. It could redirect the freed hours to maintenance, testing, or security work that had been deferred. Each path has a different employment effect, and the speedup alone does not select one.
Job counts also move for reasons unrelated to tooling, such as hiring budgets and sector demand. That is why labor analysis needs controls like the industry-shock test in the Federal Reserve paper, and why a productivity figure cannot stand in for a headcount figure.
How to test a claim that AI replaces developers
- Which outcome? Task time, self-reported tool use, output quality, or employment. A finding about one does not transfer to the others.
- Which people? Experienced open-source contributors, enterprise respondents in four countries, and coders in U.S. labor-market data each support different conclusions.
- Which design? A controlled task experiment, an online survey, or an observational labor-market analysis.
- Which tools and when? Results from early-2025 tools or 2024 survey responses do not describe later agentic workflows.
- Measured or perceived? Separate what people say they used or felt from what was timed or counted.
- Preliminary or settled? Distinguish working papers and vendor surveys from official statistics and established causal findings.
What remains unresolved
The sources reviewed do not give a reliable global estimate of how many developer jobs AI will eliminate or create over the long term. They do not establish a universal productivity multiplier, and they do not support a date by which developers would be fully replaced. Answering those questions would require longer labor-market series that separate AI effects from other causes, controlled studies of current agentic tools with stable designs, and measures of how much of the work AI actually performs in production.
