Anil Menon writes in a review of Makers for Strange Horizons:
[...] His fragments on how litigation venture funding works, on how the iced-coffee cans Sammy likes to chug contain embedded CO2 canisters, on the structure of "New Work," on what the ride is about, on how roomware will change how people live together, on whether great groups are hard to put together because flaws are multiplicative while virtues are additive, etc. etc. constitute the book's brilliant mind. These fragments are not infodumps because their purpose is not to reveal essential, tedious information. They are futuristic riffs in the best tradition of speculative thinking. I think the fragments are the real reason why Doctorow wrote the book. His ability to think up these fragments is the reason people love his blog articles, the reason why Boing Boing is such a major watering hole and the reason why this book will be read, despite its literary shortcomings.
It is unfair to criticize a book for what it does not try to be. In this case however, I will, because it points to the possibility of a new kind of writing. I think Makers would have worked better as speculative non-fiction. Ideally, speculation in a SF novel should be a means to an end, but when it becomes the end itself, then it is time to jettison the novel format. We've begun to see some early signs of such ejections. Emerging disciplines like "speculative economics" and "speculative biology" encourage speculative ideas to be worked out carefully, even elegantly, without having to invoke the clumsy paraphernalia of fiction. Is Schrödinger's "What Is Life" any less literary because it doesn't have family drama and existential angst? If an economist wants to discuss how interstellar trade would work, does she really need a space opera? If a finance theorist wishes to explore whether the theory of interest rates rules out time travel does he need to bring in a Romantic Love Interest to spoon feed us the speculation? No. Modern readers have no need of such semantic sugar. Aldous Huxley called for a fictional form that would be "a perfect fusion of the novel and the essay, a novel in which one can put all one's ideas, a novel like a hold-all." Perhaps it's possible. Speculation is independent of fiction though, and this work illustrates both positively and negatively why it's an independence worth encouraging. Sometimes the best representation of a pipe is the pipe itself.
