The impact of AI on code quality. Lots of discussion of Google’s State of DevOps findings on the same topic with more detail into what’s actually happening.
Including 2025 projections for churn and copy/paste
Stack Overflow's 2024 Developer Survey showed that 63% of professional developers are currently using AI in their development process, with another 14% saying they plan to begin using AI soon.
We examine 5 years worth of data (2020-2024), using the largest dataset that has been brought to bear (211 million changed lines across repos like Chromium and Visual Studio Code) to examine how AI Assistants influence the quality of code being written.
We observe a spike in the prevalence of duplicate code blocks, along with increases in short-term churn code, and the continued decline of moved lines (code reuse).
