À quel point l'État de droit est-il fragile ?
L'État de droit, d’ores et déjà affaibli aux États-Unis, est devenu en France une cible objective. À quel point est-il fragile ?

Few things to remember :
- Universe recap : github.com/events/unive...
- when using #GitHubCopilot focus first on your context: use Plan mode to help you !

People often ask: “How do I start with #GitHub #Copilot?”
The secret: preparation. Give Copilot #Context (instructions, prompts, agents).
In this video, I show how to create:
• Instructions from your codebase
• A prompt using Plan Mode

Still shocked talking to devs/tech folks who see GenAI as just “autocomplete + chat on steroids”
No! Once you’ve clearly defined the work—requirements , architecture, quality, validation criteria—the “AI team” does the job for you.
You’re the PM, it’s the dev squad.

Using @vscode.dev Simple Browser + #GitHub #Copilot to start, update, and debug your web app — all in chat.
- Take screenshots
- Add DOM elements to context
Nice developer flow.

From the discussions at #DevFest #Nantes 2025:
it’s time to stop coding like it’s 2022.
We’ve entered the Agentic Era — where AI understands context, follows specs, and builds with us.
Code less, think more.
