The children of the 2020's will find it inconceivable that you DON'T deliver some package to your neighbors on the way home from the grocery store :)
We are moving in the direction of cost-cutting and streamlining so much that many jobs really are going away, the prices of goods are dropping, and fewer people are working. Who would have thought, twenty years ago, that YOU would be the checkout person, and the bagger, at the supermarket? (Yes, non-USA people, they still have bag boys at many supermarkets!)
The service jobs that are not being replaced by robots, are being done by you, in the name of "self service" to lower costs - and they pass the savings on to you! ;-)
This move makes perfect sense and it is a natural progression of the trends that have been happening over the past years and decades.
