## Veille

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"*).

**Émission** : *Tech & Co Business — Le débat*, BFM Business, diffusion 2026-05-05.

## Ton

**Profile**: Short televised debate (17 minutes) on a mainstream French business TV/radio channel. Format: a journalist-host + two expert guests on set, alternating directed questions/answers, balanced speaking time, radio-friendly format (the host notes *"if you're listening to us on radio"* at the end of the broadcast, BFM Business being simultaneously TV and digital radio). Target audience: French executives (CEOs, CIOs, HR directors, IT executive committees) and the general business public interested in digital transformation.

**Style**: Classic French journalistic voice on the host's side (structured questions, follow-ups, pedagogy for the general public — *"so, precisely…"*, *"so what does that actually mean…"*, *"how did they see it, how do they perceive it?"*); on Jacquet's side, a consulting-firm / think-tank editorial-expertise register (analytical frameworks, structured vocabulary: *"conductor"*, *"arbiter"*, *"complete overhaul"*, *"real barrier to entry"*); on Girard's side, a direct practitioner-CTO register, with circulating thesis-formulas (*"writing code has become an anti-pattern"*, *"we are 1,000 but with a production capacity of 10,000"*, *"if we put 10 people to empty a dishwasher, we won't go any faster"*). Overall tone is **enthusiastic and constructive** — the host explicitly concludes *"you see, we're rather enthusiastic here about this profession"* — which defuses the fear of developers disappearing while still acknowledging the scale of the disruption.

**Elaborated metaphors**:
- ***"Code is the score, you need to master the symphony"*** (Girard, on the role of the conductor).
- ***"The arrival of AI is a mechanization of code production — if we put 10 people to empty a dishwasher, we won't go any faster"*** (Girard, on the end of the Pizza Team).
- ***"By using AI agents, the developer becomes a conductor, a manager of specialized agents… a kind of arbiter"*** (Jacquet).
- ***"It's as if you were the owner of a taxi company and had a driver who doesn't consume gas — ultimately, does he create value?"*** (Girard, on the token as fuel and usage signal).
- ***"If anything, it might be easier to create a new IT department that is already AI-agent-based than to have to transform an existing one"*** (Jacquet).
- ***"The stronger AI becomes, the more risks there are [because] we let our guard down — that's where you need to be able to control it with determinism"*** (Jacquet).
- ***"The 14-day sprint gives way to bolts, flashes — an hour, half a day"*** (Jacquet).

**Audience and authority**: BFM Business format = a mainstream audience of French executives. No external source is cited on air except an **op-ed by Sylvain Duranton (BCG X) published in *Les Échos* the same day** on *harness engineering* (mentioned in passing by Girard). No reference to Anthropic, Karpathy, Cherny, Mollick, or the global figures — this is typically a Franco-French debate that locally *re-instantiates* the theses of the global ecosystem (the role of agent manager, the end of code as a measurable deliverable, 3-10× productivity, harness/guardrails). Authority is built on two complementary postures: Jacquet = leader of a think tank of 100 French CIOs (*the voice of the French CIO community*); Girard = CTO of a 1,000-person IT services company with hands-on field experience (*the voice of the operational client*).

## Pense-betes

- **Program / source**: BFM Business, *Tech & Co Business* — "The Debate" segment, aired on 2026-05-05. Replay URL: https://www.bfmtv.com/economie/replay-emissions/01-business/video-ia-et-si-les-developpeurs-disparaissaient-05-05_VN-202605050967.html
- **Format**: 17 minutes, Brightcove video (videoId `6394717802112`), unnamed host, two guests.
- **Guests**:
- **Rémi Jacquet**, CEO of Cast Software France. Founder in 2023 of a think tank that grew from a handful to *"about a hundred CIOs"* in two years, partnered with **Cigref** and **Epita**.
- **Didier Girard**, CTO and CEO of **SFEIR** (spelled out explicitly on air: *"S-F-E-I-R"*), a French IT services company (ESN) of about 1,000 people.
- **Transcription note**: Whisper renders *"Cigref"* as *"le CYF"* (read Cigref — Club Informatique des Grandes Entreprises Françaises, an association of CIOs from large French corporations, founded in 1970). The context (a think tank of about a hundred French CIOs + consistency with the ecosystem) leaves no doubt.
- **Transcription note bis**: Whisper renders *"harness"* (English) as *"Arnest"* (*"Arnest Engineering-type solutions"*, *"op-ed on Arnest Technologies"*, *"an agent is an LLM plus Arnest"*). Read **harness / harness engineering** — a term now commonly used to describe the wrapping, control, guardrail, and orchestration layer around an LLM. See the op-ed by **Sylvain Duranton (BCG X)** in *Les Échos* the same day, mentioned on air.
- **Girard's headline thesis (most quotable)**: ***"Writing code has become an anti-pattern. Today, artificial intelligence is capable of producing code that is overall of higher quality than most engineers — this must be accepted."***
- **Jacquet's headline thesis (most quotable)**: ***"By using AI agents, the developer becomes a conductor, a manager of specialized agents, capable of carrying out a number of tasks that he delegates to his various agents — a kind of arbiter who oversees what his agents do."***
- **Why the profession is not disappearing (Girard)**: *"We will always need people who build information systems. That's a certainty. (…) We are going to delegate analytical capacity and reasoning capacity to AI, but the decision-making side will always remain on the human side."*
- **Key figures/theses**:
- AI productivity: *"2× / 3× / 5× / 10× more efficient than an engineer — it's true, it's reality"* (Girard).
- SFEIR: *"We are 1,000, but we have a production capacity of 10,000."* (Girard).
- Production cycle: *"14-day sprints → one-hour or half-day bolts"* (Jacquet).
- Pizza Team: *"if we take this 8-10 person pizza team and multiply it by 10, we get to 80-100 people — that doesn't work"* (Girard).
- Skills: *"lifespan of a skill: 10 years → 1 year"* (Jacquet).
- Cast/Cigref think tank: grew from *"a few CIOs"* in 2023 to *"about a hundred CIOs"* in 2026.
- **New roles identified**:
- **Conductor / agent manager / arbiter** (Jacquet).
- **Software architect + Product Owner merged** communicating directly with the business and taking *"full responsibility for part of the information system or an application"* (Jacquet).
- **Product engineer** (Girard): *"the person capable of creating value for a given use. Relevance will no longer be measured by the number of lines of code produced, but by the value created for a particular need."*
- Distinction maintained: ***"There will always be software engineers — the profession is not going to disappear. There are areas where human intelligence will always be relevant. But a new role is emerging, which we call the product engineer."*** (Girard).
- **Tasks delegated to agents** (Jacquet): *"coding, design, QA, DevOps, control, compliance"*.
- **HR risks identified**:
- Developers *"opposed to AI for ethical reasons"* or *"who don't trust it"*.
- Developers who *"loved writing code and won't appreciate the role of software architect / validator of generated code"*.
- *"There are people who won't necessarily have the level [required]."*
- **Token as new KPI / fuel**:
- *"The token becomes the fuel for building value."* (Girard).
- NVIDIA anecdote: *"sometimes they no longer give them bonuses, they give them tokens"* — anecdote reported by the host, described as *"amusing"* by Girard, who was not previously aware of it (to be verified independently).
- Metaphor: *"you can ask the question: in your team, you have someone who doesn't consume tokens. It's a bit like a taxi company owner whose driver doesn't consume gas — does he create value?"*.
- Reverse guardrail: *"If you deploy an AI agent to 1,000 developers and let them play with it, your token consumption can explode — you need to channel and limit AI to where it brings real value."* (Jacquet).
- **Evolution of the discipline (Jacquet)**:
- **2024**: *prompt engineering*.
- **2025**: *context engineering* — *"if you put too much into the AI, it gets lost, it degrades a bit — so here we bring it under control"*.
- **2026**: ***harness engineering*** — *"controlling the way AI moves forward"*. Cast Software explicitly positions itself on this layer.
- **Convergence with Sylvain Duranton (BCG X)**: op-ed in *Les Échos* on 2026-05-05 (the same day as the broadcast). Quote reported: ***"an agent is an LLM plus harnesses"***. The host emphasized: *"French technologies, by the way"* — an explicit sovereignty-minded positioning (Cast being a French vendor).
- **Probabilistic vs deterministic AI** (Jacquet): *"AI is a technology that performs probabilistic analysis and is fairly untamable. If you don't channel it, if you don't put guardrails in place, there is a risk. What we propose is an analysis technology that is not probabilistic but deterministic, which provides AI with a number of structured pieces of information to force it to use that information in its operating model."*
- **Structural warning (Jacquet)**: ***"The more powerful AI tools become, the more developers and teams will let their guard down. The stronger AI becomes, the more risks there are."***
- **Organizational transformation**:
- New working group within the Cast/Cigref think tank: ***a complete overhaul of the Software Development Lifecycle*** including *"all the human and organizational challenges"* (Jacquet).
- Jacquet's provocative thesis: ***"If anything, it might be easier to create a new IT department that is already AI-agent-based than to have to transform an existing one."***
- Pivotal role of HR departments: *"For me, when it comes to the success of AI adoption in organizations and IT departments, the role of HR is truly fundamental. New roles need to be reimagined."* (Jacquet).
- Job description: *"If the job description is mainly based on skills, we have an issue — because things keep changing all the time."* (Jacquet).
- **Recommendations for junior developers**:
- *"No, no, absolutely not [no reason to worry]. On the contrary, there really are positions to be taken — as long as the person has understood that they must become a conductor, a kind of software engineer."* (Jacquet).
- *"You need to develop the fundamentals of mastering software architecture — that's difficult for a young person to acquire."* (Jacquet).
- *"Code is the score. You really need to have the symphony on the conductor side."* (Girard).
- *"The act of producing code, ultimately, is no longer all that useful. You need to work on the systemic side and the overall understanding of the system."* (Girard).
- **Schools follow-up**: *"It is also up to schools at some point to review their curricula — as we discussed with Epita, who takes part in the think tank — so that profiles and skills lead IT departments to want to hire the young people coming in."* (Jacquet).
- **News mentioned**: *"we have Anthropic's tools arriving; SpaceX saying, hey, I'm going to buy Cursor"* (host, in the opening). Reference to be verified — the SpaceX/Cursor rumor is cited as one example among others of the attractiveness of the coding agents segment.
- **Host's closing verbatim**: *"We say 'developer profession,' but there are so many sub-roles within it, and Didier knows this perfectly well. You see, we're rather enthusiastic here about this profession."*
- **Listening link**: *"If you're interested, go to the Cast Software website, or Cigref's"* — to join the think tank.

## RésuméDe400mots

On the set of *Tech & Co Business* (BFM Business, May 5, 2026, "The Debate" segment, 17 minutes), Rémi Jacquet (CEO of Cast Software France, founder in 2023 of a think tank of about a hundred CIOs partnered with Cigref/Epita) and Didier Girard (CTO and CEO of SFEIR, a French IT services company of 1,000 people) compare their readings on the future of the developer profession in the age of AI agents.

Girard strikes from the outset: ***"writing code has become an anti-pattern"***. AI now produces code of higher quality than most engineers and is *"2 to 10 times more efficient"* — *"that's the reality, you have to accept it"*. But the profession is not disappearing: *"we delegate analysis and reasoning to AI, the decision remains human."* Jacquet adds: the developer becomes a ***conductor / agent manager / arbiter***, talking directly with the business and taking full responsibility for an application. The 14-day Scrum sprints give way to one-hour to half-day ***bolts***. Amazon's **Pizza Team** (8-10 people) no longer holds: *"if we put 10 people together to empty a dishwasher, we won't go any faster"* — teams need to be **segmented**. SFEIR claims *"1,000 people for a production capacity of 10,000"*. A new role is emerging — the ***product engineer*** —, measured not in lines of code but in value created.

On the risk side, Jacquet raises a counter-intuitive warning: ***"the stronger AI becomes, the more we let our guard down — the more risks there are."*** Cast positions itself on ***harness engineering***: structured **deterministic** analysis to channel **probabilistic** AI and control the code produced (architectural consistency, guardrails). Announced historical pivot: *prompt engineering* (2024) → *context engineering* (2025) → ***harness engineering*** (2026), aligned with Sylvain Duranton's (BCG X) op-ed published the same day in *Les Échos* (*"an agent = an LLM + harnesses"*) — explicitly *"French technology"*.

On the HR side, **the token becomes the fuel of value**: NVIDIA allegedly pays bonuses in tokens, *"a developer who doesn't consume tokens is like a taxi driver without gas — is he really creating value?"* The lifespan of a skill drops from **10 years to 1 year**, skills-based job descriptions falter, HR departments become pivotal to the transformation, and a new think-tank group is working on a *"complete overhaul of the SDLC"*. Jacquet's provocative thesis: *"it might be easier to create a new IT department that is already AI-agent-based than to transform an existing one."*

Finally, to juniors: *"there are positions to be taken — provided you become a conductor and master the fundamentals of software architecture."* Girard concludes: ***"code is the score — you need to master the symphony."***
