Kurzweil reviews Her Feb 18 2014
Futurist Ray Kurzweil reviews Spike Jonze's Her.
I would place some of the elements in Jonze's depiction at around 2020, give or take a couple of years, such as the diffident and insulting videogame character he interacts with, and the pin-sized cameras that one can place like a freckle on one's face. Other elements seem more like 2014, such as the flat-panel displays, notebooks and mobile devices.
Samantha herself I would place at 2029, when the leap to human-level AI would be reasonably believable. There are some incongruities, however. As I mentioned, a lot of the dramatic tension is provided by the fact that Theodore's love interest does not have a body. But this is an unrealistic notion. It would be technically trivial in the future to provide her a virtual visual presence to match her virtual auditory presence, using, lens-mounted displays, for example, that display images onto Theodore's retinas.
According to Jonze in interviews, Kurzweil's work on the singularity was a definite influence on the movie.
