If there is one thing the Chinese government does well it is law enforcement. If you make a deep fake that isn't in line with the public narrative you disappear.
I wonder how long it will be before we see people purposely create these so they can influence their descendants. There might be a future where people have "relationships" with a collection of long dead people.
AIs controlling money is the application that scares me the most, honestly, not weapons. It's flexible and attached to every section of life by design; there is no such thing as sandboxing.
Depending on how it's implemented, it might very well be one of the non-creepy uses. As long as it isn't taken to extremes, being able to have a chance to say goodbye to your loved one could be therapeutic. Or to see them once a year during the Ghost Festival to help keep their memory alive.
It does have high creepy potential (all deepfakes do), but I can understand the appeal. Make sure you take some nice videos of the people you love, and let them take some of you. Death doesn't always come with a warning, and you don't want to be wishing you had some recordings.
