Honestly with the fact ever person is essentially carrying a real time updated GPS tracker in their pockets for predictive trend tracking, there is no reason we couldn’t achieve the point of them knowing when and where you are and delivery to your hands at work/school/home/wherever. Add a “just find me” option with filters that lock out certain places like your work office and can recognize and predict your commute times. Charge a little extra and let the fedex/UPS dude act like an Uber.This. Of course, the average Walmart customer is out of breath by the time they've waddled in to a store..
If people are gonna freely cede all their personal information anyway we might as well get something good out of it.
