I loved Longitude, and Harrison was a determined guy, but the most interesting part for me was seeing the “rewrite from scratch” and “never ship” dynamics are old indeed! He had a MVP with his first iteration.
Unfortunately I got this as an audiobook and the author, who is born in the Bronx, decided for some reason to read it in a British accent which made it really hard for me to get through. Might have to get the book itself and give it another try.
