zaratustra reviewed Emergence by Steven Johnson
Review of 'Emergence' on 'Goodreads'
4 stars
Describes emergent complexity in various common decentralized systems: anthills, the human brain, cities, slime molds. Decent layman description of terms involved.
The "modern tech" sections - on my 2001 edition at least - may be slightly outdated: SimCity and eBay are mentioned, while it's weird to have Alexa mentioned as a data-mining company recently purchased by Amazon.
