re: The carbon or silicon colonization of the Universe?
The statement in this article is incorrect.
Science Fiction did predict the PC.
I refer you to a short story called
"A LOGIC NAMED JOE" by Murry Leinster, copyright
1950. Not only did Mr. Leinster predict a personal computer
in every home (called Logics in his story), but everyone's Logic
in the story is interconnected in a vast network with the
ability to search all human knowledge.
The story is humorous and explores the implications of
everyone knowing everything about each other.
