I meant something like embedding into culture where death is unnecessary, rather than directly arguing for that. Words aren't best communication channel for changing moral values. Will it be enough? I hope yes, if death of carriers of moral values isn't necessary condition for moral progress.

Edit: BTW, if CEV will be computed using humans' reflection on its application, then it means that FAI cannot passively combine all volitions, it must search for and somehow choose fixed point. Which rule should govern that process?
