When technology entrepreneur Artur Sychov’s father was diagnosed with cancer, he was forced to accept a day may soon come when he wouldn’t be able to speak to him again.

The 38-year-old knew he would give anything to have another father-son conversation after his father’s death.

So, using artificial intelligencehe got to work on a way that could make it happen for others in his position.

Artur has created a virtual reality tool called “live forever mode”. It features digital avatars who can simulate a person’s voice, mannerisms and movements after just 30 minutes of the user being observed.
