There's more than last-mile delivery, though. Amazon is automating its warehouses right now. Managing fragile and perishable goods will be an extra twist for them, but grocery stories will be starting from scratch (unless they're already working on the problem, which would be the right thing but seems unlikely.) Automated hand-off between an automated warehouse and an automated delivery platform is going to be a hard standard for grocery stores to compete with, especially on timeliness.
