Humans to become immortal cyborgs within 20 years?

Background:
This is the final novel in the Foundation Universe chronologically speaking. There are a couple short stories completed by other authors, but Foundation and Earth describes (in 494 pages) where Asimov saw his epic saga moving toward. It is a shame that he couldn’t have lived longer to continue on writing. For those that don’t know, Isaac Asimov contracted HIV from a blood transfusion during a heart operation in 1983. It later developed into AIDS, causing heart and kidney failure which led to his death in 1992. For more information on his life and death, visit Asimov Online. I wish I could remember the source, but I know I read that Asimov was not sure exactly how he would continue the series when a fan suggested he go back and write some prequels. Before his death he did fill in some gaps with the Prelude to Foundation and Forward the Foundation.

Review:
Almost no time has passed since Golan Trevize made his decision in favor of Galaxia over a Second Galactic Empire controlled by either the First or Second Foundation. Trevize is still on Gaia along with Janov Pelorat and Bliss. Golan intends to find Earth so that he can find out why he chose felt that Galaxia was best for not only mankind, but for every living thing in the Galaxy. He will not rest until he finds Earth. Bliss insists on going on his search to act as protection through her role as part of Gaia, and Janov has his own research on Earth that he wishes to complete.

The one thing that Asimov succeeds accomplishing in this novel, as he does with the others books in this series, is creating and describing different cultures. These cultures vary from the extremes of conservatism to tribal utopias. Each new world has its own customs, mythology, and history which is described through the interactions between the protagonists and the natives encountered throughout their complex journey. (more…)
