I've recently adopted the idea of Transhumanism. I find it intriguing and a logical point that follows our current technological path. I love to research the ideas involved with what a technological singularity might be like and am currently reading two books that follow along this line, Singularity Sky and Iron Sunrise both by Charles Stross. If anyone knows of some more sci-fi books that postulate on society in a advanced point in our future, please list them for me here or on my talk page :)
