The mummy example is interesting, but we're not trying to reanimate mummies in an artificial way so I'm not sure it poses the same issue. There's also an educational and historical aspect with mummies that is missing here.

This also allows for the creation of a kind of "anti-history", where someone could create a fictional history for nefarious purposes.

In fact, a common undercurrent I see with many AI use cases is accelerating the breakdown of trust in society. You can no longer trust anything you read, see, or hear.
