Cursor CEO Warns ‘Vibe Coding’ Leaves Software on Shaky Footing

He promotes an IDE-integrated, context-aware assistant that keeps developers inspecting what AI writes.

Overview

  • At the Fortune Brainstorm AI conference, Michael Truell cautioned that blindly accepting AI-generated code can cause systems to crumble as complexity grows.
  • He defined vibe coding as asking an AI to build features end to end without looking at the code or its structure.
  • Truell said Cursor embeds assistance in the editor, uses full codebase context, offers multi-line autocomplete and function generation, and helps debug and explain errors.
  • He argued AI can handle simple prototypes yet core work still demands human review, testing, documentation, and strong engineering judgment.
  • Cursor reports about 1 million daily users, roughly $1 billion in annualized revenue, and 300 employees, following an initial $8 million OpenAI Startup Fund investment and a 2025 $2.3 billion round valuing the company at $29.3 billion.
