Perhaps this is just a function that it's a marketing post designed to simultaneously appeal to different audiences while explaining the problem to decision makers that are unfamiliar with what problem they're trying to solve. I sympathize, but as a designer acutely familiar with problems around API discovery, the first half was an extremely cringey read.
Anyway, you quoted all the right sources (save for Tim Berners-Lee's Semantic Web and Giant Global Graph), and I wish you much luck, but I think you're aware that this was tried before [1][2], where much less human interaction and intervention was required, and it nonetheless faltered. "Complexity" was a scapegoat at the time, and I think that's an unsatisfactory, almost too convenient of an answer, so how do you avoid that same fate?
