When I was a kid, I read this book by I forget who (mighta been Isaac Asimov).
In it, the human race was entirely house bound, and connected up to computers. Their physical bodies had evolved and atrophied from sitting around all their life, but their heads were HUGE, cause they were so 'smart'.
Animals had either evolved, or been genetically engineered (I forget) until they were human-like, walking on two legs and speaking English.
I think they even got opposable thumbs cause they ran the world just as humans used to do, while the real humans never saw the sun or went outside.
I see many parallels in modern America and the western world. Substitute non-white, third worlders for Asimov's (?) animals and white people for humans, and he was trying to tell us something.
(is that racist?)
These Ivy Leaguer lefty derps are well on their way to Asimov's world.
(if it warn't Asimov, it was some other top sci-fi writer. Wish I could remember, I'd like to read it again).
