Even when politicians pretend to be speaking the truth, there is little veracity to their statements and little follow-up or follow-through. So having an AI or deepfake video do that for them seems like a natural next step.
If none of it is real, does it matter how it was made? Witness the massive announcements which are revoked, then reinstated, then revoked again. We are in another post-truth era in history. Myanmar used to cut newspaper articles out with scissors to censor them before delivering papers to foreigners. All propaganda is just that.
