It is totally proof of brain... not the brain concept I thought at first, but interesting nonetheless.
Why do you ask if you got it wrong from the beginning? Something important. I think it is not a fixed thing. It can evolve, as we see on each hard fork. It was not the same thing the first days, than the first month, than the first year... and it will be different next year... and the next... So... I would say... it is proof of adaptation. Now I like it more :D
