In 2023, OpenAI co-founder Andrej Karpathy stated that the most powerful programming language is English. By 2025, 41% of all global code is AI-generated, and “vibe coding” is Collins Dictionary’s Word of the Year. On 2 February 2025, Karpathy described vibe coding as a development approach where you express what you want in natural language. Searches for the term reportedly jumped 6,700% in a single quarter. The vibe coding platform market was valued at $4.7 billion in 2025, projected to reach $12.3 billion by 2027. By 2025, 84% of developers globally were using or planning to use AI coding tools, and among Y Combinator’s Winter 2025 cohort, 21% of companies had codebases that were over 90% AI-generated. Eugene Perumal, founder and principal of Valutivity, notes that the 45% security failure rate in AI-generated code is a board-level liability.
