What an epic string of posts, @lei. Your passion and painful pleas for the success of the IC are undeniable. No one can possibly accuse you and your criticisms of just spreading FUD.
At a high level, I think you would probably agree that most of your sections 1 and 2 regarding technical issues can probably be ironed out eventually, and there seem to be some positive reactions from Dom and others on those points. However, like me, I think what you are most deeply concerned about are the systemic issues in section 3 and in your Final Words post.
These issues are not only part of the root cause regarding the delays and critical fixes in sections 1 and 2, but they are also likely at the heart of why you see your dream being unavoidably shattered. In my view, all of these issues reflect a huge disconnect and power conflict over prioritization. Perhaps the biggest indicator of this conflict is how community-led priorities already approved by the NNS have been consistently delayed and put on the backburner in favor of DFINITY-led priorities.
The root cause of all this conflict comes back once again to what I have been calling the “collective prioritization chasm”, which is derived from a longstanding problem in social choice theory. It ultimately reflects the complete inability of the NNS to aggregate many competing priorities into a consistently rational list of collective priorities. To be fair, this is not just a problem for the NNS or DFINITY. It is a problem that every DAO faces and no large organization (let alone DAO) has ever solved to date.
I have offered to dedicate my time to experiment with solutions to this decentralization problem as part of my upcoming PhD, but DFINITY has declined to accept my assistance. This does not make me hopeful that this systemic conflict between the community and DFINITY will ever be solved or sufficiently reduced. In fact, it will likely only get far worse as the stakes become higher with sizable SNS token economies running on the IC. See my post here for some additional elaboration (and then perhaps we should talk further offline):
