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.

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.

I'm developing faster than ever, even if I spend less time in my IDE.
Thanks to #GitHub #Copilot and its agents, I now spend more time on what truly matters: defining architecture & specs in md.
This approach is completely reshaping how I work.
