Fundamentals still worth learning when AI writes the code
The article argues that while AI coding agents generate most of the code, developers still need to master fundamental programming concepts to effectively steer and verify these tools. It highlights ten key areas, such as HTTP, Git, and SQL, where a lack of foundational knowledge can lead to subtle errors that agents might produce. Understanding these basics allows developers to identify issues like unsafe HTTP methods or inefficient database queries that automated systems may overlook.
- ▪AI coding agents are now responsible for generating the majority of code, but human oversight is required to catch logical errors and ensure correctness.
- ▪Knowledge of HTTP semantics is critical to prevent agents from using unsafe methods like GET for data deletion, which can cause unintended side effects.
- ▪Understanding Git operations is necessary to recover from destructive commands like hard resets that agents might execute without proper context.
- ▪Familiarity with SQL and relational data structures helps developers spot performance issues like the N+1 query problem that agents frequently introduce.

Home / CareerThe 10 fundamentals still worth learning when AI writes the codeBy Flavio CopesSep 26, 2026Ten programming fundamentals that still matter when coding agents write the code: what each is, how an agent gets it wrong, and the free course that teaches it.~~~No one wants to learn to code anymore, and I understand why. I build with coding agents every day, and almost all the code I shipped since March 2026 came out of an agent. What I still use is the knowledge that lets me steer the agent, read what it produced, and catch what it got wrong. Learning to code with AI is mostly that. Here are the ten I would still study. For each: what it is, a real moment where an agent gets it wrong and only someone who knows the fundamental notices, and the free course that teaches it.
