politicians could always post their words/promises/acts in some undeletable place like nostr signed with a personal PGP-key, so the words could always be checked as actual, but it's too cypherpunk for them 

(didn't understand tho, how media taking about the power of deep fakes is connected to their leftiness lol) 

 media wants to eliminate criticism of politicians by showing videos or audio of them doing or saying something.  and deepfake education is the path to reduce the power of this.  For example Joe Biden falling down a staircase
