Unbound arrives on several shelves at once here: science and engineering, technology, politics and society, with a classics and heritage tag alongside them. Works that resist a single category usually do so because they are arguing across disciplines, and that spread of tags points at a wide lens rather than a narrow study.
We hold no verified background on the author and will not improvise any. The record does show a work that has gathered a substantial body of listener opinion in the decade since its release, a durability most non fiction never manages. Whatever else may be said about it, it has kept its audience.
