1. Acceptance. There's the saying "you just need to be more secure than your neighbor". It's not fully true but biz people hold it so. It's flip side is a cynic commentary on security, and a true one at that: If your neighbor is not secure, you don't need to be either. This is still true if you're getting pwned. When everyone's getting hacked regularly, society will accept this new reality. Only the defense sector will still care for security. We've seen similar developments in different industries: Fast fashion isn't an adequate replacement for garment that stands the test of time. But it's getting impossible to buy good clothes, even if you want to. But also with other goods: If everyone produces low quality items, it's financially more reasonable to do the same.
2. Centralization. Coz we won't do the right thing and reduce complexity, we need to find a way to make complexity "secure": Cloud, Big5, etc. Corps that have the resources to host an Exchange server securely... or in compliance with regulations. Every tool you do not let a big house host is a liability. Not coz they're necessarily more secure, but because nobody will blame you if something gets wrong. We had that with "buying IBM" once.
I hate this outlook but I seriously doubt that we will correct course.
