When do you take something for granted?
About a hundred years ago, having electricity and running water was a luxury. Receiving an electric or water connection would have brought delight to a household. Today, those things are taken for granted. Riots can break out if they are denied.
During my childhood, owning a computer with an internet connection was a luxury. Today, we take it for granted that they are basic necessities.
We have taken something for granted when its presence does not increase our happiness, but its absence makes us unhappy. Throughout human history, breakthrough inventions of a certain era have been taken for granted thereafter.
To progress is to reach for something that we don’t already have. It is a destination that always looms on the horizon, but never arrives.
