Not to say that you're making this point, but I would argue that if Bitcoin is obsolete and irrelevant than Bitcoin Cash most certainly is equally irrelevant and obsolete. The Bitcoin Cash approach to distributed database design is kind of like seeing a car with a 1kw engine, realizing that it will never be able to reach orbit, and putting a 100kw, diesel-electric hybrid engine in it instead. I think it's undeniably better, but in a direction orthogonal to what the protocol needs for long term usefulness - a more sustainable consensus mechanism with massively higher throughput.
