The concept of 'vibe coding,' introduced by OpenAI co-founder Andrej Karpathy in February 2025, is reshaping software development by enabling users to build applications with AI assistance. This approach allows individuals to create functional software by providing instructions to AI systems, such as Claude 3.5 Sonnet and ChatGPT, without requiring extensive coding expertise. Tools like windsurf.ai and the Replit mobile app have become popular for vibe coding, allowing users to rapidly prototype and build projects. Examples include creating websites, apps, and other software solutions. While this method has lowered the barrier to entry for programming, critics warn that AI-generated code often contains flaws, raising concerns about quality and security. The rise of vibe coding is also impacting the startup ecosystem, with some predicting that it could disrupt up to 95% of startups, particularly those offering convenience-based products. Venture capitalists are now prioritizing founders with domain expertise and proficiency in AI tools over traditional coding skills, reflecting the evolving definition of technical expertise in the AI era.
