I disagree. And first of all, there is a reflective meta teaching from the very idea of the "Bitter Lessons": the past reveals that (in a way) "the application of models has not been a winner" - but we cannot really know that it is not, because we do not have obtained a model out of it, a model that shows why, an explanation - epistemologically, the "discouraging" protocols cannot be made a "law". Practically, there still is a need to identify the proper architecture(s) to avoid the undesired weaknesses of the attempts in the current stages.
