If you have children, I am often surprised how they seem to think that the previous generation was stone age. Particular example is that my daughter was surprised I would give orders to my broker via fax, and that the latency was practically the same they get on the free tiers of their online 2020s bank (this is France). My trusty old ThinkPad, which still boots as if 30 years hadn't passed, still has all such digitalized sent/received faxes I did in the 90s..
I occasionally notice that people younger than me seem more impressed by smartphones than me (and I assume, maybe incorrectly, my generation).
One theory I have for this is that younger people are taught by teachers, when they are at an impressionable age, to revere the smartphone as the pinnacle of human achievement.
To me, the smartphone impressed me for a couple years, but it's just one of many miracles of miniaturization I've lived through - and less qualitatively different than, for example, personal computers or the GUI or the internet going public.
My father noticed a similar phenomenon with Rock n Roll. People younger than him saw it as a musical sea-change, but to him it just sounded like the boogie woogie music the radio already had been playing for a decade.
I was born in the early 70s, and growing up in America's Mountain West had the reverse experience until personal computers and the internet arrived in the early 90s.
From the perspective of my childhood, technology (cars, planes, phones & faxes, rockets, computers, refrigerators and other household appliances, rock music, radio, movies, television, science fiction & fantasy, the machinery of war, factories, farming, medicine, etc) were all elements of society that had advanced in technological progress, but had "always been there". I, of course, knew that there was a world before all that - my great-grandfather, who lived into his 90s and whom I got to know well, had driven a stagecoach as a teenager - but all of those had entered something like their modern form during or in the immediate aftermath of WWII, and to me it seemed like there had been progress, but not systemic change, in all the time since. It helped that all the adults around me largely saw WWII as the defining event of modern history. There was "before the War" and there was "now" (which came after the war).
Partly that was result of being born at the right time - the space program was in full swing, computers were a staple of fiction and large business but no more, the counterculture had come and gone, etc. The world really seemed like a timeless place to me as a child, and then about the time I reached adulthood, the Cold War ended, and the Internet Era arrived, and the world changed (and continued to change).
Because it was in many ways, the same as a generation before that and one before that.
40+yy ago, HIV was still a death sentence, lung cancer slid to the 3-4th position in CODs caused by cancer. Late 90s saw the introduction of gene therapies. New drugs for diabetes and heart disease came to the market. These aren't small incremental QoL improvements; these advancements saved millions of lives since then.
All this progress should be celebrated, not trivialized
At what age did you notice that? My daughter is 5 and more often than not assumes that life before her was exactly the same as she experiences. Once in a while though she’ll ask if we had iPads made of wood or something like that which is amusing.
Children in general have a very hard time grasping the idea that their parents' lives resembled their own at all. For another example, look how every generation of teenagers, without fail, thinks they are the first people in the world to invent having sex for fun. I myself didn't understand how my parents used to easily catch me in most of my attempts to get away with trouble, until I realized (as an adult) that they caught me so easily because they tried the same sorts of things as kids themselves. It's just human nature, I guess.
