I suspect we are going to see massive abuse of this technology. The Grok porn-o-bot is the tip of the iceberg. We'll be getting lots of phone calls that sound human as they try to scam us using all sorts of personal data. I've already seen people in my family get scammed by current methods. The genii is out of the bottle.
Of course it has real uses too, but you do have to be aware of the limitations.
