I understand your concerns over scalability and computational efficiency, but this is something that will work itself out in future developments of the Ethereum platform. We can’t expect to have every problem worked out from the beginning. Splitting our attention into so many different currencies and projects lacking any significant overlap is counter-productive to everyone. Look at javascript, it’s a complete mess and yet it drives nearly everything on the internet. Likewise with the limitations of the blockchain. The solution isn’t to start everything from scratch, but to iterate incrementally toward a common goal. Web 1.0, 2.0, and now 3.0 if Ethereum succeeds is the only way we are going to make progress. Ultimately, scalability and efficiency are factors that become superfluous with the agile development of the current system and the growth of computational power.  

We need to stop the fragmentation and paralysis that is destroying our planet. The only way we can do this is if we start pooling our resources into a single decentralized environment in which we can realize our varied aspirations without ideological bias preframing the system. At some point we need to settle on an architecture that solves the majority of our problems. Ethereum is the next logical step on that path. Crowdfunding superintelligence, on the other hand, while highly desirable is not immediately feasible, nor is it something we can all give universal support. I have no doubt what you are hoping for is going to happen, but it is far in the future, perhaps web 5.0 or 6.0. If you want to dedicate your life to something that is potentially decades away, fair enough and good luck to you. Personally, I think the singularity is already happening, it begins with the open society Ethereum makes possible.
