I read and watched quite a bit of sci-fi (including from the golden age) as a kid in the early 90s and don't recall such a dream. What media exactly did I overlook?
Jetsons cartoon, Back to The Future, Space Odyssey, even more distant predictions [1]? That's from the top of my head without even searching thoroughly.
So the claim is that video calls are the interesting thing, not having a touchscreen interface or having the display cover an entire surface or being a single unfolded piece? (I had been struggling to understand what was special about "from a rectangle", since non-smart phones have had raster displays for much longer.)
Yeah, that really just never figured into my visions of "the future" as anything significant, I have to say. And even nowadays it doesn't seem like people often make video calls, given the opportunity. They'd rather take advantage of those displays to doomscroll social media, or see amazingly crisp (and emoji-filled!) text in a messaging app.
The point is it was a predicted future for 100 years and now it actually is here. Gen Z actually makes video calls all the time when elders would make normal calls.
