Linux Foundation: AI halves coding time, but a quarter of new pull requests are slop
A Linux Foundation study published on Oct. 19 found that generative AI cuts coding time by about 52%. However, roughly a quarter of new pull requests are low quality, which adds to maintainers' burden.
Who is affected and how
- senior developer
- As a maintainer, it is worth introducing PR filtering rules (template, mandatory tests, disclosure of AI use) so that review time does not grow.
- tech lead
- The team's AI-assisted PRs should go through internal review before submission so that they do not burden the maintainers of external projects.
- junior developer
- Submit an AI-generated fix only after understanding the code and running the tests.
