Ok. To mee it seems no concern at all. Superior systems do not to be understood in order to work. It is enough to be able to use it and see how it works. Almost every person uses Computers, while a minority understand how they work. Still it is unthinkable, that computers could leave our world only because the most powerful loose it. Same was with the printing press. A lot of powerfull people against it. But this does not change how usefull it is. When something does the same thing but easyer and cheaper, it will always win. The question is only how long it takes. But never if it will win. The same with Bitcoin. It takes out every intermediary in a transaction between two people and has the transaction cost far below current systems. I really think there could not be a world, in which the adaption is not coming.
