But if Amazon Drones means there are literally no consequences for being ill-prepared and a careless ass - then why does the lesson need to be taught? Just as most of us now are not taught how to milk a cow or till a field, the art of being prepared is a skill of yesteryear in a world with ubiquitous drone coverage.
The important part is "a world with ubiquitous drone coverage".
There are still places where Amazon can't/won't deliver quickly by traditional means. I suspect those will also remain out of range of drones for a very long time.
Unless you are content to never travel outside of major cities, then learning to be competent in basic skills like thinking ahead are still useful for being a mostly functional human.
