This "decentralized organization" is funded for large part by a single private company, Blockstream. Now I am grateful for Blockstream for funding bitcoin development - as long as that happens in an above-board manner. But since they are by far the largest investor, and core devs are employees of Blockstream, it is false to claim there is no centralization. If there is centralization, it cannot possibly be decentralized. Bitcoin Core is, thus, not a decentralized organization.
If we leave core, bitcoin will not fail. There are many alternative clients now - Classic, Unlimitedand XT. Core Developer Gavin Andresen was entrusted by Satoshi to run the project. He is involved with bitcoin longer than any other developer. He supports a non-Core client. Jeff Garzik is also an extremely experienced core developer that is involved with those other client implementations. Even so, there are many skilled individuals in the world that could complement the team. Bitcoin is supposed to be decentralized. If it is centralized, it can be controlled. If it can be controlled, it will be controlled. If it will be controlled, it will be corrupted. If it will be corrupted, it will fail and lose its value. Thus, to maintain and grow its value, it MUST be decentralized. The biggest centralization threat is development of the core client. Bitcoin should not have a reference client.
Mr. Mow is being dishonest, OR he is driven by fear.
For everyone else - let's scale.
