I think that pitch was inevitable given the author's tagline: > Building interactive digital assets for the Metaverse. Of course the joke is that the use case is as easily solved by a database, which he even explicitly says UO didn't have. The "double spend problem" has been solved by any database that supports cluster-wide transactions and there are a number of pieces of software that implement only this aspect of a database as a part of "turning the database inside-out" (usually with only a promise of eventual consistency, e.g. implementing only a write-ahead log). Sure, a "proof of work ledger technology" could have been used but it would also have been the wrong tool for the job given that proof of work (or proof of stake for that matter) adds nothing to the solution but makes everything slower and more expensive. The only valid use cases I've heard of are interfaces between different companies and even in those cases I'm not convinced blockchain is a good solution, let alone the best one, rather than a buzzword someone used to get a raise by wooing upper management.
