Hyperpersuasion is not necessary. AI needn't convince the smartest among us, it need only convince the masses. Which, thanks to the widgets in our pockets, is a highly distributable task.

Wars are being fought drone-to-drone already without a reduction in human deaths. Every drive-by-wire car and plane is a weapon waiting to be deployed.
