Economically it makes more sense to buy cheaper and faster. But this eats into the fabric of society and offers nothing in exchange.

The same could be said of many previous innovations going back to the industrial revolution. We've always found new jobs for people and generally raised the quality of living.

    Then there's the centralisation, control and privacy part - amazon gets to decide what products your area will be supplied with, it gets to know your eating habits, your walking habits, etc. Will pretty much own you and the neighbourhood.

This is true of many grocery chains though already. They can track that information based off rewards cards and purchase history. I'm pretty sure Amazon won't be the only company to do this technology will either be replicated by other companies or turned into a service for other companies to leverage.
