# Beyond the Vibe: Specs, Adversarial Review, and Engineering AI Development that Scales and Ships


- **Date:** Thursday, Sep 24, 2026
- **Time:** 14:50–15:20 (30 min)
- **Room:** Stage 6
- **Event:** World Congress 2026 North America

## Description

Vibe coding is real, and it's useful — it's how you rapidly explore ideas and prove out concepts. But by definition, vibing means using AI for something you're not deep in yourself, and that's precisely why it can't be where production code comes from. Production starts earlier than people think: with specs that get adversarially reviewed before a single line gets written, then the engineering expertise to know what good looks like, and the agentic harnesses, domain modeling, and durable testing that enforce it at scale. AI doesn't replace that expertise — it multiplies it, letting people who already know what they're doing move faster and build better. Practical, technical, and grounded in what PwC has built and learned in production.
