"Hey Alexa, compute my weekly food/things purchase with optimized cost alternatives"... In my opinion, Amazon will be huge, and it is just starting. What worries me the most is that they will have no competition. Amazon is "killing" many small (and big) businesses because their customer service is excellent. Times when the shop make you felt like a criminal when returning defective stuff are gone, for good. And now, those small (or big) business are improving customer service. So the customer win.
