When reading anything about Ethereum, the problem I've encountered is that the authors describe the supposed potential of the technology but never practical use cases. They never talk about successful, working applications. The question for Ethereum, like any technology, is what real-world problem is it uniquely suited to solve? Personally, I don't think Ethereum will ever live up to the hype surrounding it because its founders have promised more than it can deliver.
