In this episode, I’m joined by Julien Saumande (founder of Phocéis, now a fractional CTO and organiser of the Gen AI Builders conferences) to separate myth from reality in AI-driven development.
From vibe coding to the rise of shadow IT in businesses, we explore the opportunities, security pitfalls and major economic impact of this revolution.
What you’ll discover in this episode:
Vibe Coding vs AIDD: Why coding entirely through prompts without technical expertise produces “throwaway code”, and why humans must remain the software architects.
The rise of Shadow IT: How marketing and sales teams are secretly building their own automation tools, achieving productivity gains of 30–40% while creating serious security vulnerabilities and GDPR compliance risks.
The end of the day-rate model: Why AI is undermining time-based billing in favour of token-based pricing, and how building a prototype has gone from costing €10,000 to taking just a few hours of generation.
AI security and limitations: The non-deterministic nature of algorithms, the importance of human oversight in critical systems, and the challenges of digital sovereignty.
Digital transformation for small businesses and SMEs: How to help B2B and industrial companies navigate this new ecosystem.
