Thanks  for the deep-fake links Thomas,
The deep fakes in audio and video are  ... 'Scary' and at the same time 'Fascinating!'   
I too question the content because of possible LLM hallucinations.
Well over a couple decades ago the concept of 'fuzzy logic' I had found very interesting.   Now LLM does nothing but intense fuzzy logic.   The vectors of probability are intense in these LLMs and are fuzzy login in now real widespread usage.  Of course fuzzy logic in web queries pre-dates LLM.  Get a bit too fuzzy and they hallucinate.
There are countless examples from past crime and court shows where some recording is used as evidence.   The deep fake of voice voids usage of a great many recordings as they are now so easily faked.  You can have somebody say total trash as long as your vocal model is broad enough for general speech faking.
Thanks for sharing, I now am going to seek out other examples of deep fakes as there are likely quite a few now.
