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).
