wow, so many reasons

• to create a mimic of a person you must first destroy their privacy
• after an AI has devoured all they've ever written or spoken on video it will then mimic such person very well, but most likely still be a legal property of a company that made it
• in a situation like that you'd then have to pay a subscription to interact with the mimic (because god forbid you ever get actually sold something nowadays)

now imagine having to pay to talk with a ghost of your loved one, a chatbot that sometimes allows you to forget that the actual person is gone, and makes all the moments where that illusion is broken all the more painful. A chatbot that denies you grief, and traps you in hell where you can talk with the person you lost, but never touch them, never feel them, never see them grow (or you could pay extra for the chatbot to attend new skill classes you could talk about :)).

It would make grieving impossible and take constant advantage of those who "just want to say goodbye". Grief is already hard as is, a wide spread mimicry of our dead ones would make it a psychological torture

for more information watch ~~a prediction of our future~~ a fun sci-fi show called Black Mirror, specifically the episode titled Be Right Back (entire series is fully episodic you don't need to watch from the start)
