Like Wireless, Toast is another collection of Charles Stross short stories lent to me by Janos. For me, Toast maintains a higher average standard than Wireless, although Wireless does have some cracking stories.
I hugely enjoyed Toast, and of all the sci-fi I read, these stories come the closest to my own notions about our future. Stross has been influenced by the sort of things Ray Kurzweil talks about; the singularity, computronium, uploading living things neuron by neuron.
Btw, I asked Janos the robot cars question, and he gave a considered 'no'.
