Accelerando

Stross (Singularity Sky ) explores humanity's inability to cope with molecular nanotechnology run amok in this teeming near-future SF stand-alone. In part one, "Slow Takeoff," "free enterprise broker" Manfred Macx and his soon-to-be-estranged wife/dominatrix, Pamela, lay the foundation for the next decade's transhumans. In "Point of Inflection," Amber, their punky maladjusted teenage daughter, and Sadeq Khurasani, a Muslim judge, engineer and scholar, try to escape the social chaos that antiaging treatments have wreaked on Earth by riding a tin can–sized starship via nanocomputerization to a brown dwarf star called Hyundai. The Wunch, trade-delegation aliens evolved from uploaded lobster mentalities, and Macx's grandson, Sirhan, roister through "Singularity," in which people become cybernetic constructs. Stross's three-generation experiment in stream-of-artificial-consciousness impresses, but his flat characters and inchoate rapid-fire explosions of often muzzily related ideas, theories, opinions and nightmares too often resemble intellectual pyrotechnics—breathtakingly gaudy but too brief, leaving connections lost somewhere in outer/inner/cyber space.
