Oct 22, 2025 In this conversation, Alexandre Pesant, AI lead at Lovable, delves into vibe coding, a transformative practice in software development. He explains how this approach shifts focus from typing code to expressing intent through higher-level abstractions. Alex shares insights on coding agents and the critical role of context engineering. He discusses Lovable’s evolution from complex agent systems to simpler workflows and back as technologies improved. Listeners also gain perspectives on AI's impact on engineering roles and the importance of robust evaluations in creating successful AI-native development tools.

Episode notes
English As A Programming Abstraction
- Alexandre Pesant argues that describing intent in English is becoming the new programming layer above code.
- He compares vibe coding to compiling high-level code into machine code and sees it as a natural abstraction.
Uncanny Valley Of Programming Will Resolve
- Pesant calls the current state an "uncanny valley" for programming but expects it to clear as models improve.
- He believes labs' heavy investments make broad scale success inevitable.
Context Engineering Multiplies Agent Power
- Modern agents excel at deciding the next action but need better context engineering.
- Adding targeted context each loop significantly improves agent decisions.
