As the left have taken over most colleges, I think that only thing that could stop them would be if colleges faced tremendous economic pressure because, say, online education or drastic cuts in government funds threatened the financial position of the colleges and they were forced to become more customer oriented, more oriented to producing scientific gains or to enhancing the future income of their students. Right now, elite colleges especially are in a very comfortable financial position and so face no pressure to take actions their leaders would consider distasteful which would include becoming more open to non-leftist views. I haven’t written on this.
I agree with you on x-risks. I think one of our best paths to avoiding them would be to use genetic engineering to create very smart and moral people, but most of academia hates the possibility that genes could have anything to do with intelligence or morality.
