If you liked BRB, do try to catch the movie Her which explores kinda the same plot but from a different angle. Here the main character (a woman) was already in love and hence the AI was competing in a way. In the movie, the main character (a guy) meets the new AI and gets reeled into a relationship (if we can call that) with her.
@ravionline True! I didn't realize how close they were haha.
@ravionline I know, it is kinda sad how people get involved in this situations
