The disheartening things is, though, we don't really have novel technologies (quantum crypto?) to guarantee security anymore and the existing ones will soon be exploitable on a mass scale. This is bad for internet commerce, and for internet itself as a medium. In the eyes of the layman, the internet is untrustworthy. I won't be surprised if in the future we will see closed, privately owned physical networks that guarantee security to their customers.

I think Facebook proves definitively that the layman doesn't care about "trustworthiness of the internet".

They do for anything that requires money and beyond. That's why banks etc. try hard to persuade people they have high security standards.

That will be a problem once you can by a quantum computer from the local IT shop, not while their are 5 of them in the world and you need a team of physicists to operate them.

quantum crypto is going to be available to governments first and to civilians later, if at all, ever. we should be be making plans on how to protect ourselves from the cracking powers of quantum computers with our traditional computers instead: http://www.pqcrypto.org/
