Dear Prof. Landsman,
You essay is brilliant, very important for closing loopholes and final ending with determinism in QM. The question now is where the fundamental indeterminism or randomness plus undecidability comes from. You state that theory of the Planck scale would derive QM as emergent, then hopefully we may know. Such theory, or an ultimate theory of everything should also be able to tell emerging 'why' and from 'what' and this 'what' should be then kind of irreducible or self-referential. Such topics are obviously rather mind-blowing. In my essay I am focusing on the 'why' and 'what' and it turns out it is uncomputable sequences which have curious relation with nothingness. Material in my essay is rather compressed and concepts are not stated precisely but I hope the essence can be grasped.
Best regards,
Irek
