I have a theory about the difference in attitude about household robots between East and West. To recap, people in the West seem worried, and their minds can wander toward thoughts of monsters, whereas people in the East generally seem delighted by the prospect.
My theory is that it’s a difference between Judeo-Christianity and Animism. In the West, life is God-given, and to pervert that natural order of things can seem monstrous.
That is the basic premise of the very first science fiction story — Mary Shelley’s Frankenstein. Man using technology to compete with God is an act of hubris, and that act must be met with divine punishment.
In contrast, Animism is premised on the fundamental belief that there is life in all things, whether a tree or a rock or a chair. So to bring an inanimate object to life is simply to manifest something that was already there.
