There are some recent developments that are potentially scary, but I don't see how this is one of them. Humans are really good at guessing approximate age, sex, and ethnicity from a voice. I'm not surprised in the least that some machine learning can do it too. I think the "whole of a person" is a lot more than age, sex, and ethnicity, so I don't agree that we are "getting close."
