Unlike a field expert, dude has influence, reach and an organization (with experts) in the trenches, and now decades of experience in all of the above. He’s not a couch-commenter. It’s like asking why we ought to listen anyone from Y itself here since they have zero experience with temp/vacation housing, storage, payments... all true, but they have experience with people and what and where and when to listen to. Gates is like that, multiplied by decades of experience.
