The world has changed a lot in the last decade. One of the most obvious changes is security. The reason for that is that all we do and rely on as a society is now digital and the digital age requires trust because physical things are now only represented digitally or controlled digitally and we can only trust that they exist or work, things like money, identity, availability of basic services like water and power. But, in reality, they exist and are controlled less and less physically and only reported to us digitally. In other words, we have to trust they exist!
