My interest here is the shift from science-fiction to fact - that AI - artificial intelligence on the web can and is delivering support. This will manifest itself in various ways, including support and assessment of early drafts of written assignments, possibly reading a blog to comment where others don't ... and to aid those who are isolated or at odds with the technology.
This book takes it into the realm of companions, as talking 'pets', as reflections of the user and potentially even after many years of support becoming a virtual record or avatar of the deceased.
