This book presents some very interesting ideas about the main challenges facing humankind in the 21st century and outlines some of the potential opportunities that could arise out of them. In particular, two focal points of change stand out: the "canyon" which represents the pressures of our many challenges pressing us into a single channel of crisis - and the singularity, where artificial intelligence grows beyond our ability to fully understand it.
While it makes many fine points, three large flaws limited my enjoyment somewhat. Firstly, the book is far too long and repetitive. It could be shortened by half and be fresher and more direct for it.
Secondly, it splits its story between a life before the "canyon" where it discusses our problems with great insight into our ignorance and neglect, and a second part after the "canyon" where we emerge into another world but the world afterwards has no shred of the same frailties of human nature that got us into the situation in the first place. Like many futurists before him, he sees us transcend from the Flintstones to the Jetsons, changing into something that never really looks like real human nature. This is the civilisation that was gifted the Internet and turned it into a cesspool of porn, fake news, selfies and celebrity gossip. Yet in the future we take to writing operas while our driverless hydrogen cars take us to the hydroponic farm. Who are these people? I don't recognise them at all.
And that brings me to the last and biggest flaw. For all the talk of change, Martin doesn't talk about what would really change us - and WE are what needs to change. Just as he criticises scientists for being drunk on the idea of WHAT we could achieve rather than WHETHER we really should, so Martin waxes lyrical about how we could be but (barring talk of cutting subsidies for the oil and car industry) doesn't talk about what forces could make us change and become what he dreams of. It's up to the canyon apparently - because for all his talk of acting before the crisis of the 21st century hits, he doesn't seem to have any ideas how to do that himself.
