I think it may be possible when we reach the point where our devices respond empathetically and appropriately to our interactions. Also, humans respond automatically to certain visual cues, such as large heads in proportion to bodies and large eyes, in theory because it triggers our ingrained behavior as social animals to protect the young. It helps explain why most of us see puppies and kittens as "cute". If you look at robotics designs, it is common for the designers to recognize this and build them with visual cues to appeal to this instinct.
This also raises the question of what is love. Is it the same thing to all individuals? I don’t know if it is something we all experience in the same way, anymore than I know if the red I see is the same red that you and others see. In any case, this looks like an interesting film. Spike Jonez has done some pretty cool work in the past, including Being John Malkovich, so I expect it to be pretty good.
