Dan Kois in Slate: “The Segway also reminds me of my fallibility. To this day, thinking about it fills me with dread. That’s because in 2001, I was a young literary agent—and Dean Kamen’s book was my first-ever big deal. The cascading series of miscues that tanked the Segway began with that book proposal, its leak, and the ensuing hype. And I’ve always had a sick sense that the leak was somehow my fault. So I set out to report the story, to wade back into the mess I made when I got in way over my head, and to figure out once and for all the answer to a question that’s eaten at me for 20 years: Did I kill the Segway?”
