At this point I’ve got six decades under my belt (well there is some overhang).
As far as nostalgia goes I have come to the conclusion that whatever moment in the space-time continuum we are in it is a sure bet that, “ these are the good old days”.
As Roy Batty said,
“...all those moments will be lost in time, like tears in rain.”
Rutger Hauer in the 1982 Ridley Scott film Blade Runner.
I have thought a lot about that issue - whether nostalgia is inevitable, and whether remembering "the good old days" is just a crock of you-know-what. I've come to believe that there have been certain turning points in human history where something important has been lost, and that people are often completely justified in a logical sense in missing older times.
For example, when the industrial revolution eventually overshadowed agrarianism and craftsman-based methods of production, a fruit-of-the-land lifestyle was lost to mechanization and generic one-size-fits-all standardized production. A very nature-based way of living was replaced by not-so-human industrialization. Of course the agrarian life was hard, demanding, and dangerous, and during the industrial period plenty of objectively good advancements were made in the areas of medicine, the cost of goods, and easing human burdens through technology in general. However, even though there were obvious improvements, something valuable was lost. The Southern Agrarian writers described this loss better than I ever could, so I'll defer to them on further descriptions of the matter, though I think most of them ultimately came to the conclusion that the change was a one-way deal and there is no going back. Much was improved, but something important was lost.
We've also seen a comparable arrangement of both improvement as well as loss with the advent of the internet, smartphones, and 24/7 connectedness. For example, there used to be no such thing as "after work emails." In certain corporate cultures, employees now are feeling like they are eternally on the clock due to the expectations that come with the current systems. I know first-hand that this same 24/7 connectedness issue applies in small business where some clients expect quick responses, including on weekends and after hours. Other people let their "connectedness" online interfere with their real-life relationships by focusing on their online experiences rather than sharing a moment in real time. There is also the problem of social media causing some users to have distorted expectations of what day-to-day life can be like, or of how happy and adventurous people are in general, based on people tending to only post the highlights of their lives on social media and keeping the mundane private.
Anyhow, before I ramble on too long about it, I just wanted to make the point that the 24/7 connectedness provided by technology has certainly changed certain aspects of life dramatically, both good and bad, to the extent that those of us who might say that we "miss the good old days" are completely justified and logical in our sentiments.
