LLMs Excel at Code Generation, Lack Engineering Decision-Making

TL;DR. Large Language Models can generate code but fail to perform critical engineering decisions that ensure system safety and coherence. - LLMs skip vital steps like defining requirements, modeling systems, and identifying failure modes. - This absence of engineering insight leads to brittle code that ignores constraints and invariants. - Human engineers must still define system boundaries, manage state transitions, and handle error recovery.

• LLMs generate code but do not perform the upstream engineering tasks necessary for robust systems.
• Critical engineering decisions, like defining requirements and managing failure modes, are beyond current LLM capabilities.
• Systems built solely on 'vibe coding' by LLMs will lack coherence and be prone to production failures.
