Everyone remembers where they were and what they were doing when one of the great and the good is assassinated. You can kill a politician, but their ideas usually live on.

Stross' ideas are hard, cold, pure, and funny, but it is his storytelling - the effectiveness of the complete tale - that elevates his ideas into science-fiction excellence.

"Antibodies" brings to mind Isaac Asimov's similarly elegant short story "Living Space".
