Agreed. A very interesting and thoughtful post, but I think that you are right that OpenAI's primary use cases seem to be (unsurprisingly) academic research and rapid prototyping of new ideas. These emphasize very different set of problems than, say, deploying something in production or as a service.

Thus, this post seems immensely useful to someone like me (a PhD student, also primarily concerned with exploring new ideas and getting my next conference paper), but I can see how others doing machine learning in-the-wild or in production might see a lot of questions left unanswered. I, for one, work primarily with health care data from hospital EHRs, and I spent a lot more time with data prep pipelines than folks working with, say, MNIST.
