Primary-source tech-watch digest on the position of **Gregor Hohpe** (author of *Enterprise Integration Patterns*, *The Software Architect Elevator*, *Cloud/Platform Strategy*; former AWS & Google Cloud Enterprise Strategist, former Chief Architect at Allianz) regarding the role of the architect in the era of generative AI. Thesis: AI **does not devalue** the architect, it **shifts their value** from code to what AI does not do — **making and owning decisions, arbitrating trade-offs, "selling options," communicating with humans, producing sound abstractions**. Key formula (Craft Conference 2026): "*Developers mainly interact with machines… GenAI. In contrast, architects communicate with humans*". His signature thesis (the architect should not be the smartest person in the room, they should **make everyone else smarter**) grows stronger as code becomes abundant: the advantage comes from **decision discipline** and **surfacing hidden trade-offs**, not from volume. The digest also breaks down his positions by role (enterprise architect: from **cartographer to scout**; software architect: **debugging** decisions rather than writing code; platform architect: **abstractions, not illusions**), his **real options** metaphor (value increasing with technological volatility, Black-Scholes analogy), and his warnings ("*An AI-driven SDLC punishes bad habits much faster*"; the winners of AI will be defined by how fast they move from experimentation to **governed production**). ⚠️ The widely circulated formula "architects who use AI will replace those who don't" **is not from Hohpe**. Domain: software architecture, the architect's role, decision-making, real options, platforms, GenAI in the SDLC.

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"*).
