Thanks for the comment.

Certainly ethical aspects are problematic, even if this technology is used as part of a treatment or therapy to fight mourning.

By the way, the questioning about reality led me to old memories of the classic movie Matrix and Morpheus' speech about the real hahaha, well I also remembered that at that time I remembered the discussions about the deceits of the human senses among materialist philosophers and idealist philosophers ... "reality" may be a construction we make between what we perceive and what our social group accepts as real.
