Asimov Misses Kindle's Advent by Some 26,000 Years

Sometimes I am amazed at how on-target science fiction writers from the past have been able to predict future developments in technology...and sometimes I'm just as amazed when they are terribly far off-the-mark.  Take, for example, the late Isaac Asimov's 1982 novel Foundation's Edge.  It is set some 26 thousand years into the future, when faster-than-light space travel (through "hyperspace") has been available for humanity for almost all of that time...and nuclear technology has developed on a "micro" scale.  The story's main characters of councilman Golan Trevize and historian Janov Pelorat are about to embark in space on a ship that is mentally driven, with their quest being the rediscovery of the planet Earth.  Pelorat is a rather stuffy old academician, and he wants to take his materials with him on the trip.  In italics, I have provided a short excerpt from the book at this point:

Golan Trevize asked Professor Pelorat, "Are you ready?"

"With this I am", Pelorat said and held up a square wafer about twenty centimeters to the side and encased in a jacket of silvery plastic.  Trevize was suddenly aware that Pelorat had been holding it since they had left his home, shifting it from hand to hand and never putting it down, even when they had stopped for a quick breakfast.

"What's that, Professor?"

"My library.  It's indexed by subject matter and origin and I've gotten it all into one wafer.  If you think this ship is a marvel, how about this wafer?  A whole library!  Everything I have collected!  Wonderful!  Wonderful!"

The "wafer"? I don't know how you would call it, but to me it's nothing less than a Kindle, which came out in 2007...only 25 years after the publication of Foundation's Edge.  Yet the good professor compares its level of technology favorable to the hyperspace-capable spaceship...something that in our own present minds has to be thought of as next-to-impossible.  I don't think that Isaac Asimov, not to mention other science fiction futurist writers of his era, understood the upcoming information technology revolution and how quickly and pervasively it would affect the world.  On the other hand, almost all of them had humankind traveling widely in space by our time and establishing settlements on the moon and other planets...
