Why Developers Should Be Worried About Vibe Coding
AI product development is the loudest conversation in software right now, and one of the least understood. Everyone says they are building an AI product. Very few can explain what that actually means.In this blog of The Seezoned Crew, Lucas Luengo, Director of Software Architecture at Seez, cuts through it. He explains what LLM development involves day to day, why AI coding tools like ChatGPT, Claude, GitHub Copilot, Grok, Llama and TabNine still need a human reviewing every line, how frameworks like LangChain connect models to real systems, and what actually breaks when an app scales overnight. He also makes the case that vibe coding is quietly damaging junior developer careers, and explains why prompt engineering is a smaller skill than most people think.
