@DecentralizeEconomics, I watched the Synereo youtube videos and I saw a very theoretical approach and major issues with lack of a core concern about time to market. I don't know what all the work on Ethereum/Casper has to do with Synereo at all or helping users in the social media space, other than Greg's interest in both. To me the project looks in danger of being unfocused on delivery and derailed into a vehicle to support Greg's math habit.
Greg is working with Vitalik and Vlad to develop the Ethereum 2.0 Casper blockchain, because it will also be utilized as a separate chain for Synereo.
