I don't think you understand how book reviews work. Musk does not qualify as a "space pioneer," and you would find out why if you read the whole review. Repeatedly promising colonies on Mars, reusable Starships, point-to-point rocket trips, and all of the other stuff he has promised doesn't count as pioneering -- anyone can make empty promises. He did learn how to grift for tax money, but Boeing, Lockheed, et al got their a long time ago.
