Her, I think does a great job.

It's not perfect though, there are lots of weird things you have to do in movies/stories to move the plot forward, and to help the audience engage. Like, Joaquin Phoenix has a weird job. Spoilers he writes personal letters on behalf of other people? - but that job is a great setup to highlight the encroachment of Samantha's capabilities in creative roles. She never takes over for his job, she starts off by mostly just helping and giving feedback/notes. She even helps compile his best stuff into a book, which feels increasingly close to the capabilities of language models today. But she also does art, makes music - the sort of stuff in traditional sci fi that is almost taboo to position AI as being able to excel at.

I also really liked the video game Joaquin plays, the controls look... Dumb, but the idea of characters that are "alive" feeling and that you converse with seems like something people are actively currently working on with the beginnings of success.

And just the idea of an OS AI seems increasingly likely. But I think we'll exceed that in the next decade. We'll have AI that writes customized applications for us, on the fly. You want a new reddit app that also integrates Twitter? Sure. Anyway, tangents aside, Her is just a great movie to rewatch with the rise of chatbots.
