I have said this recently on another thread, (concerning shunning), and I will say it again here.
The WT is a social meme, or organism that has evolved precisely because of very specific attributes that work together and interact with each other, and the environment that they exist in. If any one of these critical attrbutes is removed or changed, the interaction of those parts change. This would likely break the "working" formula the WT has used for the last 135 or so years, and as a result, it would implode in relatively short order. The structure of assemblies is another one of these many required attributes, and will not change.
What often appears to be the biggest problems for the WT, (such as mind numbing talks, guilt trips, judgmentalism, shunning, etc.), are the very things that have kept it running all of those years. The key difference, is the environment, or society at large, has changed. This presents the biggest threat to the organization in the long run, and will cause its eventual collapse. The best and brightest are the ones filing out, as these ones are a subset of society at large.
