My favorite is the 83-year-old AI grandma on youtube giving retirement advice. They put her in various settings and she looks and sounds very real.
The only obvious tell is the eyes don't track right. But once they fix that, it's really going to be hard to know.
All the comments are how great her advice is, etc.
Every video has a link to a book she "wrote" on amazon. I didn't waste my time trying to figure out what the scam is.
