Very good presentation, and very good analogies to get the general public attention. I think the key points are: - Data allows the projection of stereotypes on everything you might be involved. - Rating systems create unwanted incentives. I don't think social credit systems are crazy, but they are extremely dangerous and easy to get wrong. Their memory should be limited, and their use should be controlled, opt-in, show-to-see, or whatever might be relevant.
