Still, I think Sam ought to see the writing on the wall regardless when people come out en-masse to say "this is kinda creepy, dude." It feels pretty obvious to me that his behavior is verging on obsessive and definitely toeing the line of technology fetishism.
That's just my impression, though ¯\_(ツ)_/¯
HER is not a horror movie. It’s about a very helpful AI assistant, and in the movie people fall in love with it.
It would be really cool to have ScarJo voice the AI, which is obviously why she was asked. She didn’t want to, so they just hired another, different person to do it.
ScarJos voice is not some super unique cornerstone of the product (obviously, since they didn’t even use it), and it seems like having her associated would be for marketing purposes. Imagine her presenting at their product demo, and talking to “herself”.
All of this feels like people are really reaching for reasons to hate Sama. In your case you aren’t even familiar with the movie people are talking about.
