I think these predictions are a logical consequence of the beliefs I hold.
They lead to a perspective and understanding of reality, that renders certain imagined possibilities - impossible.
I can make a value judgement as to whether this a preferred scenario - but that is neither here nor there.
Reality will be as it is.
I could understand if someone dislikes a set of predictions,
they may seek to disprove them.
I struggle to imagine how one could definitively prove or disprove determinism.
I think it’s unfalsifiable.
