It is up to him to add proof in any way, shape or form to his claims
No, it is not 'up to him' if he wants to actually call it a 'quote' and be a 'scientist'.
He even inserted a very cute smiley into his "quote" which Satoshi did not make.
I'm sorry, i can't take this serious. I hope he can correct his comment, remove the smiley and insert the link to the source. Before that, we can't elaborate on it, i'm sorry.
