Grieving the passing of loved ones is a great pain for every person, followed by intense emotional coping. In the modern digital age, artificial intelligence (AI) technology enables more and more immersive real-time interactions with simulations of deceased people based on available data about them. The strong emotional factor of grief can push people to generate demand for such services, leading to attachment issues on personal levels, and markets of “grief tech” on collective levels, whether open or hidden. The growth of such technologies and services may eventually lead to new formal regulations, social norms, and ethical perceptions. This can be the start of the normalization process of “Cyber-necromancy”, which carries major implications for human values in the face of potential digital immortality.
