My notes from the recent YC Vibe Coding video

The founders’ quotes at the beginning were the best part:

Notes from video:

  • Shift in Software Engineering Roles:
    The role of a software engineer is transitioning towards that of a “product engineer,” where human taste and product sense are more critical than ever.

  • Debugging Challenges: Current AI tools are not very effective at debugging, requiring human intervention to identify and fix issues.

  • Coding Style Changes: With AI making code generation cheaper, developers are more willing to rewrite code from scratch rather than debugging.

  • Tools and Models
    • Cursor is the leading IDE among the surveyed founders, but Windsurf is emerging as a strong competitor.
    • Windsurf is gaining popularity because it indexes the entire codebase, unlike Cursor, which requires specifying which files to examine.

  • AI-Generated Code Percentage: A quarter of the surveyed founders estimated that over 95% of their codebase was generated by AI.

  • Implications for Hiring
    • The focus may shift from assessing coding speed to evaluating taste, debugging skills, and system design abilities.
    • The ability to use AI tools effectively may become a key skill to screen for in technical assessments.

  • Future of Software Engineering
    • Vibe coding is suited for rapid prototyping and achieving product-market fit (zero to one).
    • Scaling and building robust systems (one to N) will still require strong systems engineering skills.
    • Exceptional engineers will need deliberate practice to master the details and understand the underlying systems.

  • Importance of Technical Depth:
    Technical founders need to be able to understand and critique the code generated by AI or written by others to avoid being misled.

  • Exponential Acceleration: The pace of change in coding is rapidly accelerating, with AI tools providing exponential gains in productivity.
