Can AI Help Maintain Open Source? A Look at Copilot with Sugar Desktop
The article explores whether GitHub Copilot can help maintain and modernize older open-source software, using Sugar Desktop as a real-world test case. You take an older Sugar activity built with Python 2 and outdated Sugar/GTK APIs and use Copilot to help migrate parts of it to a more modern codebase. Copilot performs well on generic programming tasks like updating Python syntax, changing imports, and suggesting cleaner code patterns. Where it struggles is with Sugar-specific knowledge. It has difficulty understanding older Sugar APIs, project conventions, and obsolete dependencies like Gnash. This shows that AI can speed up routine maintenance work, but it still depends heavily on maintainers who understand the project, its history, and its ecosystem. The main takeaway is: AI can reduce some of the workload involved in maintaining open source, especially repetitive modernization tasks, but it cannot yet replace the context and domain knowledge of experienced maintainers.
