What is there to like in this? It’s almost like they took their inspiration from dystopian novels. Take the decentralised vision of bitcoin and invert it to a centralised system. Aggregate biometric data on a massive scale with those who “opt in” having no sense of what they are giving up for the pittance they are receiving. This all brought to us by the same person who has told us that his latest tech hit has a very real capacity to destroy the human race. It like an entry in the competition to become the next Bond villain.
