"The foundation and its subsidiaries alone simply do not have the manpower to push the entirety of this vision through to its ultimate completion, including proof-of-stake driven scalable blockchains, seamlessly integrated distributed hash tables, programming languages with formal verification systems backed by state-of-the-art theorem provers and dozens of categories of middleware, all by itself; although the foundation and its subsidiaries can, and will, continue to be the primary driver of technology at the core, a highly community-driven model is necessary and essential, both to help the Ethereum ecosystem maximally grow and flourish and to establish Ethereum as a decentralized project which is ultimately owned by all of humanity, and not any one group."
