Nanotechnology. The New Victorians. Future fantasy, grounded in real science...

I am rereading The Diamond Age, Neal Stephenson's classic and wonderful book set in a nanotech-centric future. It's a marvel. I read it shortly after it was published, and it amazes me in reading it now how many of the wild, nearly-absurd things he predicted in this book and in Snowcrash, have actually come true. 

Amazing.
