Vibe coding demos great. Then production arrives.

Karpathy coined "vibe coding" in Feb 2025. 13 months later he called it passé. His replacement term: agentic engineering. The difference isn't the tools. It's who owns the judgment.

Vibe coding: prompt → accept → ship → pray. Agentic engineering: define goals → let agents execute → YOU review the logic → ship. One of these collapses under real data. The other scales.

I've been building ML pipelines hands-on. LightGBM. Optuna tuning. Imbalanced datasets. Threshold optimization. AI didn't catch the edge cases. I did. That's the part vibe coding skips.
