Eloi - in Dan Simmons's Ilium

In Dan Simmons's Ilium

In Dan Simmons's Ilium novel, 'Eloi' is a nickname for the lazy, uneducated, and uncultured descendants of the human race after the post-humans have left Earth. The name is a reference to H. G. Wells's Eloi.

Old-style humans and post-humans rule in Simmons's novel, with the Eloi being kept in 'zoos' in restricted areas on Earth. The Eloi are technically adept but don't understand the technology; they regress and unlearn millennia of culture, thought and reason, until they are satisfied with the pleasure of merely existing.
