Even better than Glasshouse in its portrayal of a technological singularity. I have no idea how many of the concepts were invented by Stross himself, but if you are at all interested in the pace of technological advances and a vision of where it could one day lead: this is your book.

But be prepared: it's nerdy, the vocabulary can become quite technical and the weirdness factor is rather high. This book needs a lot of concentration, definitely not an easy read but very worthwhile.
