My apologies. I'm going to answer in English. My French is so-so.
I think such a committee would be table stakes and, to be honest, I'm not totally sure it would change things much one way or another.
For the larger question of how governments should react, there are two schools of thought. One is just don't build AGI, but that requires global coordination, and it's a very tall order. More generally, upgrading our institutions across the board to be more robustly aligned to humans is a huge task. No one knows how to do it. It could benefit from AI helping us to build better forecasts or better coordination mechanisms. It's something that no one has had to do because we've always been needed by the states, but the only plausible way I can see forward, if we do make ourselves irrelevant by AGI, is that we could be okay in principle if, along the way, we managed to rethink the incentives that our governments face and build much more robust control mechanisms that make sure that citizens can't be marginalized permanently.
