If there is a decent usecase for AI, AR and VR combined, it is to be able to get us to experience how we will feel in the future, given our current track. Imagine being able to live the life as an eighty year old you for a few days, when you are twenty.
The problem is, people will instead use it to make themselves feel better now, so they can ignore their actual health.
Convenience and languishing certainly is a slippery slope huh?
Anything to distract us from doing what we actually need.
