My inspiration to this is from one of of my favorite movies

I was thinking about an A.I apllication to portraits of deceaed people make their likeness in to the potraits. So you can talk to them and they to you. Remember in harry potter the potraits on hogwarts they move they react and can move from places to places. A normal picture or video i think is still to hard for now or too disturbing in the future. Here is the explanation

Portraits were paintings made of certain individuals, namely witches and wizards.[1] The subject of a magical portrait was sentient due to enchantments placed on the portrait by the painter. The portrait would be able to use some of the subject's favourite phrases and imitate their general demeanour based on how the subject appeared to the painter; however, they were limited in what they could say or do.[2] A portrait could also move from portrait to portrait, or else visit a portrait of them elsewhere in the world.

I think it would be verry cool to have your own painting like this and then you talk to the painting for a few hours a week and it would become your companion and when your dead. Your loved onces could talk to your likeness in diffrent ways to diffent people . Check and see the movie scenes you would get what i mean
