There are not and can't be any decentralized projects on planet Earth because our solar system is extremely centralized because (1) the sun is a single point of failure in our system (if it fails, so does everything including our decentralized project), (2) we depend on the sun and hope that it will not burn us, in fact it is an authoritarian system, which means that is antithetical to the very concept of decentralized systems, (3) the systems that we build on Earth matter neither for the sun nor the Universe. In short, Bitcoin doesn't make sense and solves no real problems of universal scale.
...as of now. As long as we have ISP's who grants us access to the internet, or any part of that internet, hardware-wise and otherwise, is controlled by any central authority or produced non open source.
Do you know you can become your own ISP and grant access to yourself?
No, I didn't know that, but it being possible makes sense.
Otherwise, I enjoy your reflection of my description above. My purpose here is not to criticise, but to see what Ideas could possibly be valid in the future when the next step of the evolution in decentralisation is due. We, as a civilisation, seldom look forward, but seem to stride to keep things as they are, until a next step i forced by crisis or stimulated by genius breakthrough. Without ideas beyond where we are at in any given moment, there is no future but a repetition of the past.
