That's not creepy
Futurology
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.
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.
It'll be fun seeing LLMs have control over whether or not descendants get access to the family trust fund...
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.
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.
