Can you imagine how cool it would be if a million or, say, a hundred million people joined forces to do what a $60 mobile phone can do?
This is absolutely the future. No doubt about it. No one can ever conceivably come up with a paradigm as cool as this level of redundancy. And on top of all of this, it even works. (Not as designed, because 51% of miners may be controlled by one entity, but in practice it totally works.)
