But I'm confident the overall system of higher education will be here long after I'm dead. Well, you get the idea. There is no sudden cut off point before which things are pre-programmed and beyond which the future suddenly becomes completely ontologically uncertain. The further into the future we look, the more our knowledge of that future is general, the less it is particular. If we look sufficiently far forward, we can know only such things as that humans will still be of weak character and massy objects will still attract by the inverse square law.
Ontological uncertainty is a matter of degree.
It is my impression that your argument underplays this point. I hope these comments are sensible. I look forward to your reply.
