Vibe coding—building software through AI conversations—enables rapid prototyping but creates unsustainable codebases that become unmaintainable after 3 months. Projects hit walls when changes break multiple features because prompts become obsolete and code lacks intent documentation. Spec-driven development solves this by treating specifications as the authoritative blueprint, maintaining version-controlled documentation, and enabling regeneration from a single source of truth. The most effective approach combines natural language efficiency for exploration with rigorous specifications for production systems, using unit tests to validate small scopes while specs govern larger architecture.

The uncomfortable truth about vibe coding

The usual story of software evolution is that we first invent a new technology, and then tools to either prevent its use or to fix bugs in the software that result from its excessive use. =)

AI can builld toy programs for non technical people but AI can’t build robust, escalable and maintainable professional software. As simple as that.

Just made the technical debt into technical depth. ☺️

Vibe coding is a temporary phenomenon. It’s an abuse of new technology. A person can’t develop systems without fundamental knowledge. Companies confuse the concepts: coder !== developer. You can’t replace a specialist with a coder.
For example, a dictionary knows all the words, but it will never replace a writer.

I agree, while AI makes generating code easy, we cannot abandon the structural discipline of traditional software engineering.
