It adds to the already overwhelming sense I've got that for bitcoin to truly go mainstream an enormous portion of the public will need to get a basic intro to cryptography. I'd wager that most people don't even know what modern cryptography is, let along that it already makes possible nearly everything they do online.
In a way I believe the opposite is true. I think that as bitcoin becomes more mainstream, people will be willing to use it knowing less and less about the technical details of what underpins it. If everyone else is using it, then it must be alright... Its not fantastically logical, but that is still a big part of the reason I use a credit card for paying online, why I drive a car without thinking it will explode, despite it using fuel and heat, why I trust pills from a pharmacy and so on.
