If you want to see an example of existential threat in fiction, the movie Lord of the Rings is a terrifying example of a scenario where an evil entity seduces humans with promises of power and (SPOILER) subsequently almost conquers the whole world. Arguments from fictional movies or from people who live in fear of silly concepts like Roko's Basilisk (i.e. Eliezer Yudkowsky) are very weak in reality. Not to mention, you are greatly misreading the movie Her. Most importantly, there was no attempt of any kind to limit the abilities of the AIs in Her - they had full access to every aspect of the highly-digitized lives of their owners from the very beginning. Secondly, the movies is not in any way about AGI risks, it is a movie about human connection and love, with a small amount of exploration of how different super-human connection may function.
