If Amazon completely replaces local retail...which is looking more and more likely...what will our streets start to look like?

What if we begin to not only have a bunch of empty warehouse big-box stores (ex-Kmarts, Best Buys and Circuit City's), but a bunch of smaller empty buildings, too?

Because, in this seemingly inevitable future of instant online-to-real-life gratification, what does a town really need to have nearby?

Restaurants and fresh food grocers (aside from the non-perishables that can now be delivered same-day), and basic service locations, e.g. gas station, hair salon, dentist?

All other retail gone?

It's crazy to think about what a town will look in 10 years. And to think about what we're going to do with all those buildings...
