You are both close, but missing it. Cicada isn't a cult. It isn't a government, it isn't banks. It isn't all of Satoshi Nakamoto. (although members are undoubtedly involved in each of these areas).
Cicada is fundamentally about evolution of man. About taking us to the next step. Not the next biological step (although that's part of it too). It's more than that. It's about man overcoming humanity. Digging deep inside to find infinity. Realizing all out limitations, weakness, and suffering are our own creations.
We live in a Matrix-like world and they're here to pull out the few who see past it, and then guide them further down the path. Except our matrix isn't a computer program built by machines. Our matrix is the belief that we even exist in the first place. Our egos built our matrixes. But we can't see it because our egos have convinced us that they ARE us.
The Cicada revolution occurs on every level: physical, subconscious, emotional, mental, social, technical, and on.
Those who find their way to the enlightenment offered are those who will change the world of, not just tomorrow, but the world of today.
