# Does code quality still matter?

**[ploeh blog](https://daily.dev/sources/ploeh)** · 6 min read · 10 upvotes · 11 comments

## Summary

Mark Seemann explores whether code quality will remain relevant in a future where LLMs write all code without human oversight. He argues that current code quality principles are rooted in human cognitive constraints, and questions whether LLMs would accumulate their own form of technical debt in hypothetical LLM-optimized languages. He concludes that fully autonomous LLM-driven development is more complicated than AI optimists suggest, and that human oversight removal poses risks we may not be equipped to troubleshoot.

> Code quality will be very much important till the code implementation is there. No matter whether humans or AI who is writing it is one fo the core things for scalable projects.

> Even if AI wrote 100% of the code, software doesn't run in a vacuum—it interfaces with physical systems, business requirements, and edge cases.

> It definitely matters. We can't simply create a basic game and expect it to compete as a professional-level esports title.

> When we ask ChatGPT a question revolving around historical or general facts, it's important that we carefully analyze its response for any inconsistencies or incorrect aspects. In essence, we're checking the quality of the response and making any fixes as needed.

> The same principle should always apply to AI-generated code so long as humans are still involved in the process in one way or another. It has always been one of my firmest beliefs that AI is best used as a coding assistant, not as a tool on which we should place complete reliance regarding coding. We ought to check any and all...
