It'd be great if someone from CFAR could spell out the case for its having a large positive impact (on the things we ultimately care about, such as human welfare). If I understand it correctly, Anna's post suggests that CFAR will do good by creating a highly effective community of do-gooders, but this would benefit from a bit more substantiation. For example, could CFAR give some specific cases in which their training has increased the ultimate good done by its recipients? And could someone fully describe a typical or representative story by which CFAR training increases human welfare?
