I&#x27;m not OP, but I think you&#x27;re misreading their comment.  Their point, if I read it correctly, is not about the technical correctness of the ML in place, but the sociological effects.  You can see this happening already: I&#x27;m sure FB&#x27;s machine learning algos that they use to filter the stream are &#x27;correct&#x27; in some way, but their effect is insidious and polarising on the way we consume information.
