Among Developers, Seniority Has Little Impact on Tool Usage

Among professional developers, the use and perception of AI are not so much a matter of seniority.

One could interpret Stack Overflow’s latest annual survey this way. It invites, in any case, consideration of the level of professional experience in many respects.

Illustration on the question « Do you use AI-based tools in your development process? ».

2024 2025 – overall 2025 – 1 to 5 years (6360 respondents) 2025 – 5 to 10 years (5997 respondents) 2025 – more than 10 years (13,001 respondents)
Yes 63.2% 80.8% 73.6% 69.6% 64.5%
Daily usage 50.6% 55.5% 52.8% 47.3%
Weekly usage 17.4% 18.1% 16.8% 17.2%
Less frequent 12.8% 11.5% 13.5% 13%
Envisaged 13.5% 4.6% 2.5% 3.7% 6%
Not envisaged 23.4% 14.7% 12.3% 13.1% 16.5%

If we focus on professional developers (26,004 respondents), the rate of “yes” reaches 80.8%, compared to 63.2% last year. In contrast, only 14.7% now say they are not interested (vs 23.4%).

Daily use is somewhat more common among the younger profiles, who are also the ones least likely to rule out using such tools.

A form of prudence among the heaviest users

On certain points, Stack Overflow distinguishes between developers who use AI tools in a “majority” of their workflows and those who use them only “partially.”

This applies to the question “Which parts of your workflow do you currently perform with AI tools?”

Task 2024 2025 – majority (11,202 respondents) 2025 – partial (20,991 respondents)
Code writing 82% 16.9% 59%
Answer searching 67.5% 54.1% 55.8%
Debugging 56.7% 20.7% 47.1%
Code documentation 40.1% 30.8% 30.3%
Generation of content or synthetic data 34.8% 35.8% 28.6%
Learning codebase 30.9% 20.8% 32.7%
Code testing 27.2% 17.9% 27.5%
Commit/code review 13.2% 10.2% 22.6%
Project planning 12.2% 10.8% 17.1%
Predictive analytics 5.3% 11% 12.7%
Deployment and monitoring 4.5% 6.2% 10.5%
Learning concepts or technologies 33.1% 47.4%
Creating or maintaining docs 24.8% 27.3%

From year to year, the hierarchy of uses has changed little. The gap between the most mature and the least mature users has narrowed, especially when including the notion of “partial” usage.

Monitoring and predictive analytics, minority usage even among contemplated uses

Among those who do not use AI tools for the tasks in question, but who plan to do so, the situation is as follows:

Task 2024 2025 – majority planned (12,790 respondents) 2025 – partial planned (22,518 respondents)
Code writing 9.2% 12.4% 32.4%
Answer searching 17.6% 17.2% 24%
Debugging 25.9% 14.8% 30.9%
Code documentation 38.2% 28.6% 30.5%
Generation of content or synthetic data 33.1% 28.9% 28%
Learning codebase 40.6% 23.1% 34.9%
Code testing 46.2% 25.8% 34.7%
Commit/code review 40.9% 16.3% 31.4%
Project planning 31.7% 14.3% 24.8%
Predictive analytics 39.8% 23% 25%
Deployment and monitoring 39.6% 15.1% 25%
Learning concepts or technologies 15.7% 27.9%
Creating or maintaining docs 31.8% 32.5%

It should be noted that the time window has evolved from one survey to the next. In 2024, Stack Overflow looked at planned uses for the coming year. This time, respondents were asked to project over a 3- to 5-year horizon.

A growing reluctance to AI that grows without exception

There are 25,349 who do not intend to use AI for at least one of the tasks. Specifically:

Task 2024 2025
Code writing 5.9% 28.9%
Answer searching 8.1% 19.6%
Debugging 9.1% 36.4%
Code documentation 12.7% 38.5%
Generation of content or synthetic data 18.7% 38.2%
Learning codebase 18.7% 39.4%
Test code 17.1% 44.1%
Commit/code review 32.9% 58.7%
Project planning 42.3% 69.2%
Predictive analytics 38.7% 65.6%
Deployment and monitoring 40.6% 75.8%
Learning concepts or technologies 32.2%
Creating or maintaining docs 39.6%

Reluctance grows without exception. They are twice as many to exclude using AI to generate content or synthetic data. Three times more for documenting code. Four times more for debugging. And almost five times more for writing.

A confidence not yet fully earned

Meanwhile, developers remain many in thinking that the AI tools they use handle complex tasks poorly

2024 2025 – overall 2025 – 1 to 5 years (6258 respondents) 2025 – 5 to 10 years (5922 respondents) 2025 – more than 10 years (12,901 respondents)
Very confident 2.9% 3.9% 4% 4% 3.6%
Fairly confident 31.5% 25.2% 28.1% 25.4% 23.5%
Neither confident nor skeptical 20.9% 14.2% 13.4% 13.8% 14.9%
Not confident 32.3% 22.8% 23.6% 23.9% 22.1%
Very unconfident 12.5% 18.6% 19.2% 19.5% 17.9%

As for problems and frustrations stemming from using AI tools, developers cited mainly in 2024:

  • Lack of trust in the answers (66.2%)
  • Inability to integrate the business context (63.3%)
  • Inadequate policies to reduce security risks (31.5%)
  • Lack of training on new tools (30.7%)
  • Work generated by these tools (12.9%)

This year, the items have changed. The lack of trust remains pervasive (66% lament the “almost right” solutions). As well as the work generated (45.2% cite the time spent debugging generated code). Some also tend to lose confidence in their own ability to solve problems (20%). There are also difficulties in understanding how and why the generated code works (16.3%).

Agents perceived as beneficial but not revolutionary

Stack Overflow defines an AI agent as “an autonomous software entity that can operate with little to no human intervention using AI techniques.” Based on this definition, 14.9% of professional developers (base: 31,877 respondents) say they use them daily. 9.2% weekly. 7.7% less often.
17.2% plan to use them; 36.7% do not. An additional 14.2% of respondents say they use them “only as copilots or for semi-automatic data entry.”

Across tools, professional developers (base: 31,636 respondents) are 16.3% to say their work has been disrupted “to a great extent.” 35.3% feel it is “rather so.” 41.4% judge that not at all or only minimally.

If we look at a sample of AI agents users (12,823 responses), a majority agree on several benefits:

  • Reduction in time spent on specific development tasks (70.1%)
  • Increase in productivity (68.7%)
  • More effective resolution of complex problems (64.2%)
  • Faster learning of technologies and codebases (63.2%)

They are, however, fewer than half to agree on the following:

  • Automation of repetitive tasks (49%)
  • Improvement in code quality (37.5%)
  • Enhancement of team collaboration (17.3%)
