An unfortunate disappointment, Hop, Skip, Go undersells on the technology to focus more on the most depressing aspect of any revolution: its financing.
Hop, Skip, Go describes itself as a book about "us", the operators of vehicles and travelers through space. Sadly, it is instead absorbed with venture capitalists and investment banks, the least relatable social class. I do not envy the book its subject, as the topic of "mobility advancements we'll see in the near future" limits it heavily to the miniscule class of ideas which can be imagined currently, but are not absurd enough to be dismissed out of hand. As a result, the book only ever touches on a couple of ideas which actually struck me as interesting-- not the gravest sin for a book focused on how mobility affects us, but a death blow to the book as it exists. With more of an interest in the ways humans react to infrastructure and mobility, these few reasonable advancements could have been the impetus for a fascinating discussion, but the author's M.O. is rather to summarize 2-5 pages of history, introduce a billionaire, and wax about how much of a visionary they are. Throughout the book, we meet exactly one inventor, and even they have left their job for an investment bank by the end of the chapter. For a target audience of people who think Elon Musk is both cool and the smartest man alive, this might find play. But instead, it just leaves the text feeling hollow.
