I had another idea, but it's buried in my head again. Therefore this suggestion, but it contains a big spoiler: Ex Machina (2015), written by Alex Garland "Ava!" Ava abandons Caleb, but she couldn't care less. She doesn't even give him a respond or an explanation. It's no real dialogue but Caleb's expression of shock. Trailer: https://www.youtube.com/watch?v=PI8XBKb6DQk Trivia: Director Alex Garland has described the future presented in the film as "ten minutes from now," meaning, "If somebody like Google or Apple announced tomorrow that they had made Ava, we would all be surprised, but we wouldn't be that surprised."

Great one, Katha. So love this movie!
