In the 1960's we were at the top of the curve for transportation technology, with space travel happening for the first time. In one lifetime people had gone from steam trains + horses to jet aircraft and humans landing on the moon. So if you look at the narratives of the time, it was that we would soon have flying cars, moon colonies, the future would be "the Jetsons." Meanwhile people did not anticipate the telecommunication and computing revolutions that were just over the horizon. Watch 2001 and one of the characters takes a commercial flight to the moon on a Pan-Am spaceship, but then makes a (video) phone call from a pay phone booth on the ship. WOW!
I think today we are in the same space on the computer revolution. Our sci-fi stores today tend toward either magical or dystopian AI, androids, etc. Ready Player One, etc. But really, the next great surge is biotech. What if we could develop biological products in the same way we develop electronic products? Who can even imagine what good and bad things that would bring about, and how profoundly the world around us could change?
I think there's a great chance that young adults today will have a life experience much like people born around 1900 did - that someday our grandchildren will ask us what life was like and our childhood without (biotech revolution) will sound as impossibly antiquated to them as life without cell phones and the internet sounds to children today.
