A rewatch for this 2013 film, about a man falling in love with his artificially intelligent operating system. The protagonist is a man called Theodore Twombly, making a living by writing heartfelt personalised letters on behalf of other people (beautifullyhandwrittenletters.com) and living on his own whilst going through a painful divorce. He installs a new operating system on his computer (that quaintly comes on a disc with an instruction leaflet) that promises to revolutionise his life by adapting and learning from him. After answering some personal questions and selecting the female voice, he finds himself in conversation with his new companion as she sorts through his old emails and organises his contacts.
He starts to form an attachment to Samantha (as the AI decides to call herself), which quickly grows into romance and even sexual feelings. I remember a great deal of scepticism at the time (and also expressed by some of the other characters) that someone would possibly have a meaningful relationship with an AI, but evidently many people are now doing exactly that.
Perhaps the most science fictional element is that his conversation is picked up perfectly by his wireless earbuds (did we have those in 2013?) without the usual palaver of "Alexa, switch the light on" "I'm sorry, I couldn't find a device or group called light". Director Spike Jonze also completely missed the obvious conclusion that the only reason a software company would release an AI operating system is so that they could hoover up as much personal data as possible to send targeted ads and political propaganda to the user as they can.
