It’s a worthwhile read for taking seriously the task of changing our political economy to meet the challenges of climate change, and is admirably guillotine-y. But it’s kind of barely a story, more of an unusually imaginative PowerPoint. The main characters are fine, the sketch characters are fine to good, but the recurring ancillary characters are nothing. And KSR has some overoptimistic ideas about blockchain that are annoying to encounter in an otherwise more-grounded-than-usual thought experiment.
