We are getting to the point where the technology that fuels oppression, including extremely pervasive surveillance, privatized intelligence services with no oversight, scalable AI agents that do as they are told, and crowd "maiming" or other forceful dispersal techniques are growing past the ability to resist them.
Wars historically happened under conditions where people died but the planet was largely left in tact, but we now have 3 countries with the ability to erase entire cities or make the world functionally uninhabitable by humans, which absolutely changes the calculus of war. If you do not have nukes your sovereignty is questionable.
Likewise if the tools to put down crowds, find saboteurs, and weed out dissent is perfected, meaningful dissent can only be expressed through withdrawal and there is no final check on abuses of power where any, instead of some, of the "checkers" of power are left in tact. Anti-dissent technology has the potential for a nuclear moment that fundamentally changes the calculus of protest and I think AI is very much potentially that.
