Reminds me of “ghost hacking” as pioneered in Ghost in the Shell franchise. Entire personalities and belief systems embedded into a person. The rise in parasocial relationships verges close to fulfilling the ghost hacking premise of implanting a belief in an entire wife and kid that don’t exist, or at least not as such. That franchise was a warning, but it’s also an instruction manual for a high tech dystopia that no one even realizes isn’t a utopia.
