Linus Torvalds says AI boosts programmer productivity but can't replace human understanding of code, system architecture at Open Source Summit keynote.

The New Stack is a publication covering trends and technologies in cloud-native development, DevOps, and software delivery. Developers can learn about containerization, Kubernetes, and cloud computing, as well as explore topics such as microservices architecture, serverless computing, and continuous integration/continuous delivery (CI/CD) pipelines.

The New Stack

At the Open Source Summit North America keynote, Linus Torvalds pushed back on claims that AI writes most code, comparing AI to compilers as a productivity tool rather than a replacement for human understanding. He argued that developers must still deeply understand systems to use AI effectively, and that those who don't will produce failing code. Torvalds also raised concerns about AI-generated pull requests and 'drive-by' bug reports flooding open-source maintainers — especially smaller projects — causing burnout. He noted a ~20% increase in Linux kernel submissions tied to AI use, and criticized companies that use AI to find bugs publicly without providing patches.

Why Linux creator Linus Torvalds gets angry hearing “99% of code is AI”

THAT IS SO TRUE WE GOT LINUS SAYING IT OMG

I strongly agree with this take, blind “vibe coding” is literally waste of time. At least know the basics of the programming language you’re using before attempting to use AI to assist you, Because Ai is prone of error and with knowledge of the language damage control is easier for ai-generated failure code.

vibe coding some small projects as an idea is ok. Vibe coding entire systems or subsystems is not even close to a good idea. So, yeah, I agree with him.
