Curiosity to Addiction

The film "Be Right Back" features a young couple, Ash and Martha. From the first couple of scenes, they do not seem like a very happy couple. Ash is always on his phone/social media, late described in the film as a "heavy user" as if it was an addiction, and is never listening to what Martha says. Ash dies in a car accident, presumably from being on the phone while driving, leaving Martha pregnant. At Ash's funeral, one of her close friends introduces her a technology that creates an artificial version of Ash using all the information found on his social media accounts. She refuses to use this program, but later, after being filled with feelings of depression and loneliness, she caves in. At first, the interaction with the artificial intelligence version of Ash, Ash2, was curious. Most of the communication was through chat/text and eventually phone calls. She starts developing feelings for this IA and gets more and more attached to it. At one point, she becomes too attached to it, you can see this when she was coming out of her doctor's appointment and she dropped her phone. She completely freaked out when she thought she was going to lose Ash 2 if the phone had broke. When she picked up her phone she told Ash 2 "I dropped you" as if he was a real person. You can see that at that moment, that curiosity was turning into an addiction. Later in the film, she buys a "real" version of Ash, an android identical to Ash. In my opinion, this is like a drug. After the first time you try it, you end up wanting more and more. Her feeling of losing Ash cloud her judgment. This eventually becomes a sick obsession. She rather interact with A2 that with other real people. Because of having Ash 2, Martha is not able to have a healthy grieving process. At the end of the film, Martha realizes that Ash 2 will never be Ash 1. A2 is only a representation of the life A1 showed online. They don't have the same feelings and is unable to replicate their emotional connection.
How far will we go with technology? If she was able to create an artificial version of Ash using his social media accounts, what is to stop other people from creating IA versions of us? Is this film a warning of the future?
