The paradigm of fixed identity information as proof is pretty obviously doomed. Just like how the 1970s concept of username/password as proof of identity is on its way out. Or credit card numbers alone being used to validate transactions.
All of those notions are pre-internet ways of proving identity. In a world where we're all rarely more than an arm's length from a globally connected computer, they're on the way out.
