5If you're going to vibe code, why not do it in C?
- Stephen Ramsay explores the tension between traditional programming and AI-assisted "vibe coding." While initially resistant to AI coding assistance, he acknowledges its effectiveness and questions why we use human-friendly programming languages when AI could work directly with lower-level code like assembly, proposing the concept of "vibe-oriented programming languages."
Requirements gathering vs. coding
Discussion centers on how the biggest bottleneck in software development isn't coding but articulating clear requirements. Backend developers struggle with vague specs from PMs and frontend teams, making AI coding assistance less useful than solving the fundamental communication problem.Language choice for AI-generated code
Debate over whether memory-safe languages like Rust provide better guardrails for LLM-generated code versus lower-level languages like C. Users argue that type systems and compile-time checks help catch AI mistakes, while others question if LLMs can handle complex memory management.Limitations and reality of vibe coding
Users share mixed experiences with "vibe coding" - describing features in natural language to AI. Many report initial excitement followed by frustration with constant clarifications, brain-melting stop-start cycles, and preference for traditional coding with AI assistance for specific tasks.
