I understand that the arguments both for and against the current DKIM regime are fairly nontrivial (should we analyse it as a loss of rights to the public (your past emails can be attributed to you) or a gain (you can hold the powerful to account)?), but either way, it seems that the only position that is consistent with the author's would be one that is enthusiastically in favour of improvement and proliferation of DeepFake technology. After all, we already live in a world where technology has created a novel form of attribution that could be used for blackmail: slightly over 100 years ago, nobody could prove or disprove that you said or did something in the past, whereas nowadays a video (given some pixel-level forensics) works as irrevokable proof positive.
