I see only the problem of no ability to change the OKRs, otherwise the core idea of making a plan is right. Changing the goals should introduce a additional change process, because priorities change with new knowledge. I haven't see that done well yet. Maybe just having 6 weeks cycle OKR [1] instead could work better as in Shape Up?
I read about criticism of General Relativity, that I haven't verified so grain of salt please. The criticism is in that the equations are so complex that only the simplest limits of them are studied and so the theory is therefore not verified.
True problem is not technical and it is right there in the article. Non-academics "speak less and worry more". So their knowledge is likely scattered and not distilled. Building these devices is probably quite simple in the end, it is just the story is not being told.
