IA : et si les développeurs disparaissaient ? — Tech & Co Business, Le débat (BFM Business, 05/05)
Televised debate on BFM Business (*Tech & Co Business* program, "The Debate" segment, 17 minutes) with **Rémi Jacquet** (CEO of Cast Software France, founder in 2023 of a think tank of about a hundred CIOs on the impact of generative AI on development, partnership with Cigref / Epita) and **Didier Girard** (CTO and CEO of **SFEIR**, a French IT services company (ESN) of about 1,000 people). Strong theses: *"writing code has become an anti-pattern"* (Girard), AI produces code of higher quality than most engineers and is *"2 to 10× more efficient"* — this is a reality, but the profession is not disappearing. The developer becomes a **conductor / agent manager / arbiter**, 14-day sprints are replaced by one-hour to half-day ***bolts***, the **Pizza Team** (8-10 people) no longer works in the agentic era, a new role is emerging — the ***product engineer*** —, the lifespan of a skill drops from **10 years to 1 year**, and **token** consumption becomes the *fuel* of value creation (NVIDIA anecdote allegedly paying bonuses in tokens, taxi driver metaphor for a driver who doesn't consume gas). SFEIR claims *"1,000 people, production capacity of 10,000"*. On the Cast side: positioning on ***harness engineering*** (deterministic vs probabilistic AI, control and guardrails), aligned with Sylvain Duranton's (BCG X) op-ed in *Les Échos* stating that *"an agent = an LLM + harnesses"*. Historical pivot: 2024 *prompt engineering* → 2025 *context engineering* → 2026 *harness engineering*. Key warning: *"the stronger AI becomes, the more we let our guard down — the more risks there are"* (Jacquet). Pivotal role of HR in the transformation, complete overhaul of the SDLC, recommendation to juniors to solidify software architecture fundamentals (*"code is the score, you need to master the symphony"*).
