Security is on Time Period Zero (Day Zero, and Year Zero didn't really seem to be the right terms). What we need in Crpyto is awareness and ubiquitous use. Additionally, it is not a fast moving concept. It will be long periods of sweat and churning before the internet is reasonably safe to use (I use the word reasonably, because anyone familiar with security understands that Perfect Security is not feasible. Rather we strive for security with negligible chance of failure).

If nothing else, Bitcoin as a protocol is a ray of hope for cryptography. If a digital crypto-currency ever becomes widely used, then crypto will become embedded in everyone's daily life (whether they're on Facebook and Gmail or not).

Public-Private Key Crypto is a concept that has only been in practice for less than 50 years. It has yet to be fully understood and implemented.
