Key Points

  • Vibe Coding is an AI-driven programming approach popularized by Andrej Karpathy (proposed in Feb 2025), where developers describe desired outcomes in natural language and the AI generates, tests, and iterates on code in a “see → say → run” loop.
  • The article contrasts Vibe Coding with traditional programming by emphasizing that users avoid writing or debugging code line-by-line, instead focusing on whether the result “feels right” and directing the AI to adjust discrepancies.
  • It cites a compelling example from Karpathy, who built and deployed a calorie-tracking iOS app to his phone within about an hour using only AI-assisted, multi-turn ChatGPT guidance—despite having zero Swift experience.
  • The piece argues that Vibe Coding is best suited for MVPs, prototypes, and small tools, while recommending traditional programming for high-security, regulated systems and large, multi-person collaborative projects.
  • As of 2026, the article claims 41% of code is now AI-generated and notes that Silicon Valley has started advertising “Vibe Coder” roles with salaries reportedly up to $120,000 per year.
