We're entering a world where deep fakes are not going to go away. The idea of setting up sock puppet accounts not going away. These are realities, and they're with us now for the long hall. And so we need to build in high schools, in colleges, training programmes that help people be alert to the possibility that they're being influenced by fake content. Yes, we've done this before, and we can do it again. The effects will be slow, but they will be real. And our democracy depends on them. Soi i have an example of a kind of program dhad actually worked quite well. It's an experiment by a professor named david yang.
