You're positing a possible explanation and insisting it's the only explanation, retard.
Why would Vinny ever bring up the ex-wife of a friend and associate? One who was also involved in the gaming sphere? Double retard.
Again, you're showing how much you lack technical knowledge on something you're trying to act knowledgeable about. I never insinuated it's an "AI deepfake", but there exist countless Vinny soundboards, premade, to pull all sorts of voice clips. Seriously, google "vinesauce soundboard". Search it on google play or whatever app store. You're also overstating how hard it is to do a shitty audio chopjob, which is "moreso than the screenshot fuckery, but not by a large margin". Triple retard.
This is also, of course, ignoring the Occam's Razor answer of a potential impersonator, which the following point would assist in covering for massively.
Again, assuming one potential answer must be the only possible one. Quad retard. Plus, again, perfect for covering imperfections in an impersonator.
And yet again, plausible does not equal definite, or even likely. Quintuple retard.
In short, you are making a positive claim, and ergo the burden of proof is on you. You did an astoundingly shit job at it. You dense motherfucker.
