Postsingular

It all begins next year in California. A maladjusted computer industry billionaire and a somewhat crazy US President initiate a radical transformation of the world through sentient nanotechnology; sort of the equivalent of biological artificial intelligence. At first, they succeed, but their plans are reversed by Chu, an autistic boy. The next time it isn't so easy to stop them. Most of the story takes place in a world after a heretofore unimaginable transformation, where all the things look the same but all the people are different (they're able to read each other’s minds, for starters). Travel to and from other nearby worlds in the quantum universe is possible, so now our world is visited by giant humanoids from another quantum universe, and some of them mean to tidy up the mess we've made. Or, maybe just run things.

After the Singularity, everyone and everything is sentient and telepathic. Aliens notice and invade Earth. In Rucker's last novel, Postsingular, the Singularity happened and life on Earth was transformed by the awakening of all matter into consciousness and into telepathic communication. The most intimate moments of your life can be experienced, by anyone who cares to pay attention, or by hundreds of thousands of anyones, if you are one of the Founders who helped create the Singularity. The small bunch of Founders, including young newlyweds Thuy, a hypertext novelist, and Jayjay, a gamer and brain-enhancement addict, are living a popular, live-action media life. But, now alien races that have already gone through this transformation notice Earth for the first time, and begin to arrive to exploit both the new environment and any available humans. Some of them are real estate developers, some are slavers, and some just want to help. But, how to tell the difference? Someone has to save humanity from the alien invasions, and it might as well be reality media stars Thuy and Jayjay.
