Linus Torvalds: AI Won’t Replace Understanding Code

Linus Torvalds shares his perspective on AI in software development, particularly its impact on the Linux kernel and open source projects. He acknowledges AI as a useful tool — comparable to compilers or assemblers — but warns it doesn't replace the need to understand code. He highlights a growing burnout problem among open source maintainers caused by low-quality, AI-generated bug reports and drive-by contributions. Torvalds advocates for local AI tools to avoid dependency on big tech, and stresses that developers who truly understand systems will use AI effectively, while those who don't will produce failing code. He distinguishes between throwaway 'vibe coding' projects and serious long-term software that requires deep understanding beyond just writing prompts.
