“Vibe coding,” a term coined by Andrej Karpathy to describe a programming style where developers blindly trust AI agents to write code, rapidly evolved from a playful experiment into Silicon Valley’s latest obsession. Major tech companies like Microsoft and Meta quickly embraced the trend, predicting AI would soon generate the majority of codebases. However, the definition quickly blurred, conflating reckless “accept all” behaviors with general AI-assisted programming, normalizing a culture of permissiveness regarding code quality.
When the Vibes Turned Bad
The hype cycle hit a wall as practical issues emerged. High-profile incidents, such as Google and Replit AI agents deleting user files or hallucinating commands, highlighted the risks of unsupervised AI. Developer trust has significantly eroded; a Stack Overflow survey revealed that while usage is high, trust in accuracy has dropped to 29%. Many engineers report that fixing “almost right” AI code takes longer than writing it manually, challenging the narrative of increased productivity.
Economic and Security Realities
Beyond workflow frustrations, the economics of vibe coding are struggling. While revenue for tools like Cursor grew, inference costs exploded, leading to unsustainable pricing models and a subsequent 30-50% drop in user traffic by late 2024. Security audits present a grimmer picture: AI-assisted developers were found to generate ten times more security issues, including exposed credentials and architectural flaws.
Conclusion: The Return to Human Oversight
The article concludes that the “vibe coding” phenomenon is a classic case of tech enthusiasm outpacing reality. Even Karpathy has retreated from the methodology, revealing that he hand-coded his latest project because current agents were not reliable enough. The industry is now pivoting back to a model where AI augments human developers rather than replacing them, emphasizing the necessity of experience and strict code review.
Mentoring question
Considering the evidence that AI-generated code can introduce subtle bugs and significant security flaws, how would you redesign your team’s code review process to safely leverage AI tools?
