In this episode of the Lex Fridman Podcast, AI researcher Lex Fridman hosts the founders of Cursor, an AI-assisted code editor, to discuss AI's transformative impact on programming. As a modified version of VS Code, Cursor seeks to overcome the limitations of current tools like GitHub Copilot by innovating and enhancing coding productivity through features like Cursor Tab and code diffs. The conversation explores the challenges and strategies in AI tool development, including prompt engineering, speculative edits, and cache optimization. Broader implications for programming's future are considered, such as synthetic data, reinforcement learning, and potential breakthroughs in theorem proving.
