Ray Kurzweil's review of Her
A good read: The excerpt is a criticism I share with most futuristic scifi movies, as I pointed out in the "most realistic scifi future" thread.
More realistic, but imperfect
There have been other attempts to show AIs as humans (albeit not biological) that you can have a relationship with; for example, Steven Spielberg’s 2001 film AI. That movie suffered from an all-too-common flaw of science futurism movies: it introduced a single futuristic technology — human-level cyborgs — onto an otherwise unchanged world. Her is better in this dimension, although not completely successful. It does portray a somewhat futuristic world in which the leap to human-level AIs is not so implausible.
It is far better to grasp the universe as it really is than to persist in delusion, however satisfying and reassuring. Carl Sagan
