I admit I'd been taking deepfakes with a grain of salt, thinking they couldn't be all that good. Then I watched this example of President Biden saying stuff I absolutely know even he wouldn't say and I am convinced I was wrong. It sounds like Biden and he appears to be doing the talking.
Much as I'd love for him to have said it, I know it is a fake of such quality as to be indistinguishable from the real thing, except for two things. Those are the content - what they have him saying - and the deepfake Biden makes fewer goofs and gaffes.
Because of this last difference Biden ought to hire the folks who did this deepfake and have them build out his speeches. He'd be perceived as much more with it.
