For many years, I've claimed to some of my friends that the goal of Amazon is to get to the point where they can order things for us before we even know that we want them. So Amazon wouldn't even require a confirmation on our part. We'll just come home to the packages that Amazon has decided that we need or want.
This situation raises a whole host of issues, and I'm not claiming it'd be a good thing. It just seems to me like the obvious endgame for Amazon, and I think it perfectly fits the modern ethos of reducing friction and pursuing convenience at all costs, including losing our own agency.
