'Vibe Coding' is the new danger: AI hallucinations in development

TLDR: Vibe coding is a new development style where engineers work directly with AI tools — writing code by feel, not structure. The danger: AI hallucinations cause massive bugs — the model says it works, but in reality, it doesn't. Why this matters for us: Brown developers are adopting vibe coding fast — but the tools are not yet reliable for production.
