Avatars
With that kind of technology (3-D conferencing, memory transfer, AI) it's surprising that they didn't simply alter her appearance on her videos. We can almost do that now, so 50-75 years into the future it will be a routine thing. Heck you won't be able to trust any audio or video as being the real thing. Just morph her into the "young face" needed to represent their services.
The other thing is, who would want to do it? I die so that an imperfect copy of me in a healthy body may carry on? Hm, I suppose when I'm about to die and I need a trusted heir to carry on the business or take care of an infirm loved one, it might make sense. Or do they keep it a secret that one's consciousness doesn't make it into the new body?
These nitpicks aside, it was a beautiful and thought provoking film. The notion that millions of highly intelligent, well educated people would be hopelessly outmoded and redundant because of AI, the vast poverty amidst amazing technology and enormous wealth, stupid and evil corporatocracy dominating a withered, inhuman society, are powerful images and a warning that we are closer to dystopia than we like to think.
