An advanced DAO (decentralized/distributed autonomous organization), the way Vitalik images it, is a pretty believable candidate for an uncontrolled seed AI, so I'm not sure Eliezer and co shares Vitalik's apparent enthusiasm regarding the convergence of these two sets of ideas.
I don't think so. They're running on the blockchain, which slows them down. The primary decision-making mechanisms for them are going to basically be the same as can be used for existing organizations, like democracy, prediction markets, etc. Unless you think your bank or government is going to become a seed AI, there's not that much more to DAOs.
The cryptocurrency ethereum is mentioned here occasionally, and I'm not surprised to see an overlap in interests from that sphere. Vitalik Buterin has recently published a blog post discussing some ideas regarding how smart contracts can be used to enforce superrationality in the real world, and which cases those actually are.
