I don't think that's true.

Credit cards, paypal and all the rest existed before bitcoin. I mean it's nifty that I can do it without a single intermediary authority, but it's not that special.

I think the lack of revocation available to bitcoin is a (and I had myself for saying this) 'a feature'. If somebody sends me payment in bitcoin, I definitely know it can't be charged-back for example. It's like sending cash in the mail. Now that comes with the flip side, that they are putting all their trust in me.
