About competence, there are references in the next post about the Foundations of Power.
I've seen the debate between them several years ago but I remember, i was shocked by the unfair move of Foucault changing the rules of the game when it starts, in a way to diminish Chomsky thought and intervention.(But anyway he could understand French very well.
Most of the French sociologists and utopists have always embedded the French way of thinking everything in the light of the bureaucratic influence of their culture, based in the power of signature and paper rules consolidating a Power that only wants to revive the death of France's influence in the destinies of the world.
Chomsky is more concerned with how to change and act against power, while Foucault is focused on the metaphysical analysis of power as a voyeur that do not interfere.
Chomsky for me was always a more consistent view with the frame of intervention in the social order.
But I'll be back to the panopticon of Foucault to show the concept of surveillance and control of the masses.
Macron is using again the language of violence to be seen as an ally in US/UK monks of war and to restore a deceased and moribund empire.
