Vibe Coding Produces Code, But Engineering Produces Reliable Systems

By

1d ago· 5 min readenOpinion

Summary

This article argues that "vibe coding" (using AI/LLMs to generate code without engineering rigor) produces code but not reliable systems. It contrasts the speed of AI-generated code with the critical thinking, requirement analysis, and architectural decisions that professional engineering provides. The author warns that LLMs cannot anticipate edge cases, security vulnerabilities, or system-level constraints, making vibe coding insufficient for production-grade software. The piece is a defense of engineering discipline in the age of AI-assisted development.

Vibe coding produces code. Engineering produces systems.
A model can generate a login system in seconds. It will not ask if emails must be unique. That single missing requirement can collapse the system.
LLMs cannot see the category of questions that keep software safe.
What vibe coding gives you is code. It gives you output. It gives you momentum. What it does not give you is coherence.
Before any code exists, engineers make the decisions that keep systems safe.

LLMs generate code, but they cannot see the engineering decisions that keep systems safe.
