To understand how much I enjoyed Mark Stevenson‘s An Optimist’s Tour of the Future, the first thing you need to know is that after I borrowed it from the library and read it, I went out and bought a copy and read it again just four months later. In my life as an unstoppable devourer of literature, this was a first. Usually a couple of years pass before I re-read even the most beloved of books, since my reading lists are so long that they give birth to baby-reading lists who in turn have baby-readings lists of their own in the time that it takes me to get through them.
Of all the cool things described in this book, there is not one word about jetpacks. Why they put one on the cover, I might never know.
However, a few aspects of An Optimist’s Tour proved completely irresistible and demanded an immediate re-read.
First, the number of new scientific ideas and emergent technologies that are described, accessibly and engagingly in this book, is incredible. Did you know there are several different research groups who’ve successfully created genetically engineered bacteria that consume waste CO2 and excrete fuel, such as diesel or ethanol? Or that an AI has learned not only how to derive new scientific laws, given a bunch of raw data, but also how to explain the meaning of the results it found to its creators?
None of the ideas in the book are hypothetical. In the course of writing it, Mark Stevenson visited (a very impressive roster of) research labs and startups that have conducted successful experiments with and built working prototypes of some mind-blowing technologies. From flexible solar film printed quickly and cheaply in big rolls on a former photographic printer, to nano-coating which can protect anything from clothes to monuments from weathering and dirt, the stuff of science fiction is being made manifest today in laboratories around the world.
The second aspect that makes An Optimist’s Tour of the Future such an enjoyable read, is how damned optimistic it is. In startling contrast to most books dealing with the subject of the near future, this one maintains an unwaveringly positive outlook about the success of and the possibilities offered by these nascent technologies. Lucidly and rationally, (but often excitedly, because it’s going to be so bloody cool when it ramps up and really gets going), Stevenson explains the potential of each technology to transform the lives of individuals, societies, and the planet for the better.
