AI coding tools can make it easier to produce code, but that does not automatically make it easier to learn programming. A 2026 meta-analysis found a moderate average productivity benefit across the studies it examined, while its average result for measured learning was not statistically significant. That is not evidence that AI harms learning—or that every developer gets faster. It points to a more useful question: which parts of coding are you asking the tool to do, and which are you still practicing yourself?
What does the evidence say about productivity and learning?
They are separate outcomes. A tool can help someone finish a task sooner without showing that they understand the code or can reproduce the skill later. The studies summarized here measured productivity with task-related outcomes such as completion time, commits, and lines of code; the meta-analysis measured learning with exam performance. Those measures answer different questions.

The pooled results show a modest average productivity benefit, not a guarantee
A 2026 meta-analysis by Sebastian Maier, Moritz Gunzenhäuser, Jonas Schweisthal, Manuel Schneider, and Stefan Feuerriegel included 23 studies and 27 effect sizes comparing AI-assisted with unassisted programming. Across those studies, the estimated productivity effect was moderate (Hedges’ g = 0.33; 95% CI [0.09, 0.58]), with substantial variation between settings. Gains tended to be larger in controlled experiments and smaller in open-source and enterprise contexts. The estimate is an average across studies meeting the authors’ criteria, not a prediction for an individual task or workflow. Read the meta-analysis.
The pooled learning result was inconclusive
For learning, the same meta-analysis estimated an effect of g = 0.14 (95% CI [-0.18, 0.47]), which was not statistically significant. This does not establish that AI makes learning harder, nor does it prove that AI has no effect. It means the studies included did not show a statistically clear average effect on their measured learning outcome. Exam performance also cannot settle every question about longer-term retention or applying skills independently in new situations.

Why can coding feel easier even when learning is uncertain?
AI can reduce the effort of producing a working-looking answer: it may draft code, suggest a fix, or explain an error. But if the tool supplies the key decisions and implementation, the learner has less opportunity to practice making those decisions. That is a plausible learning trade-off, not a universal causal result established by the studies here. The practical distinction is between using AI to support your thinking and using it to replace the work through which you develop skill.
How much the tool does matters. Inline completions, hints, explanations, and debugging questions leave different amounts of work to the learner than an agent asked to plan, write, and run a solution. So does the task: a short, well-defined exercise is not the same setting as changing code in a mature repository. When judging a claim about AI and coding, check the outcome measured, who took part, the setting, tool and date, whether results were observed or self-reported, and how much autonomy the AI had.
Why might AI fail to make experienced developers faster?
A randomized METR field study offers a useful counterexample to the assumption that AI always speeds up coding. It enrolled 16 experienced contributors to large open-source repositories. Participants proposed 246 real issues in repositories they had contributed to for years, and tasks averaged about two hours. In the AI-allowed condition, developers could choose tools; they primarily used Cursor Pro with Claude 3.5 or 3.7 Sonnet, tools available at the time of the early-2025 study. On average, those tasks took 19% longer.
Before the study, participants expected a 24% speed-up; afterward, they still estimated a 20% speed-up. The gap between perceived and observed speed is a reason to distinguish confidence from measured performance. The result applies to this study’s experienced developers, task selection, repository context, and tool era—not to beginners, all programming work, or later tool versions. Read METR’s study report.
What do developer surveys tell us—and what can’t they prove?
Surveys help show how developers use AI and what they think about it. They do not, by themselves, establish whether a person learned more, retained a skill, or became faster on comparable work.
| Survey finding | What it represents |
|---|---|
| In Stack Overflow’s 2024 survey analysis, 76% of all respondents said they were using or planned to use AI tools in development that year. The figures were 83.48% among people learning to code and 76.61% among professional developers. | Reported adoption or plans, not a test of learning effectiveness. Among current users, 77.34% of the learning-to-code group and 84.76% of professionals used AI to write code; 72.81% and 68.92%, respectively, used it to search for answers. Source. |
| In a separate 2024 Stack Overflow pulse survey, 38% of developers said code assistants gave inaccurate information half the time or more. | A self-reported concern. Respondents pointed to issues involving context, complexity, and less-common tools; satisfaction or perceived productivity does not independently verify correctness. Source. |
| In a 2023 survey commissioned by GitHub and conducted by Wakefield Research, 57% of 500 non-student, U.S.-based developers at companies with more than 1,000 employees said AI coding tools helped them develop coding-language skills. | A reported perception among an enterprise sample, not a test of retained knowledge or unaided coding. The article was authored by GitHub’s Chief Product Officer and GitHub staff, so its commercial perspective is relevant context. Source. |
| In an October 6, 2026 announcement, Stack Overflow said more than 30,000 people responded to its survey over seven weeks. It reported that 73% of respondents who use AI coding assistants or agents use them daily, and that 52% of respondents are still learning new coding skills. | Survey figures reported in the announcement, not causal evidence. The article also said 70% ask an AI agent for answers and 83% use a search engine. Stack Overflow said the full dataset would be published later, so these figures should be read as announcement-level findings rather than a fully inspectable dataset. Source. |
These findings show that AI use is common and that developers report both perceived benefits and accuracy problems. They do not resolve whether AI makes a particular learner more capable over time.

How can you use AI without handing over the practice?
For a learner, a useful default is to ask AI for explanation and debugging guidance while keeping implementation and verification in your own hands. That is practical advice, not a proven intervention: the available evidence does not establish that this workflow reliably improves learning for everyone.
- Predict first. Before asking for help, write down what you expect the code to do or what you think is causing the error.
- Ask for a hint or explanation. Ask the assistant to explain a concept, identify the relevant part of an error, or suggest what to inspect before asking it to write the solution.
- Do the implementation work. Write or change the code yourself, then run it and inspect the result.
- Check the answer independently. Test edge cases and verify that the explanation matches the code and the behavior you observe. Do not treat a confident-sounding response as proof of correctness.
- Explain the result in your own words. If you cannot describe why the code works or how you would debug it, revisit the relevant concept rather than moving on just because the output looks right.
GitHub’s learning guide describes a tutor-style Copilot setup: disable inline suggestions and instruct Copilot to explain concepts without providing solutions. It is a concrete configuration example, not comparative proof that the setup improves learning. See GitHub’s learning guide.
Best Value
So, is AI making coding easier but learning harder?
It can make code production easier in some contexts, but the average productivity benefit is moderate and varies by setting. The available pooled evidence does not show a statistically significant average effect on measured learning, and it cannot establish a general learning penalty. Your best safeguard is to preserve the parts of the work that build understanding: predict, implement, debug, explain, and verify rather than accepting a completed answer you cannot account for.
