There is no “causal, dynamic origin of [quantum] uncertainty”. Quantum randomness is not about being unable to predict the numeric outcome of a many-step complex dynamic process involving many intermediate numbers. Instead, quantum randomness is about being unable to predict the numeric outcome of a single-step process. Quantum randomness is about being unable to predict the very next step, the very next real-world numeric outcome. That is the “problem” with the real physical world, from the point of view of physics.
Rather than quantum uncertainty being due to underlying complex dynamics, the reverse is true: when looked at very, very closely, real-world complex dynamics are just a series of individual quantum jump events. When looked at very closely, there is no such thing as a perfectly smooth transition of one outcome to another outcome, there are only jumps. However, before and after quantum events, the numbers that apply to the various categories, like relative position or mass or energy, are always found to be in the correct ratios, as specified by physics’ experimentally derived law of nature relationships.
Cause is a very simple, clear concept, with an uncomplicated meaning. Cause: a person or thing that gives rise to an action, phenomenon, or condition. Dynamics don’t really cause anything, because real-world dynamics are just a lot of individual events. The word “cause” can only apply to single-step number-jump events.
So, what is the cause of a single number jump? Do living things and other matter actually jump some of their own numbers, i.e. do they have a hand in causing their own physical outcomes, e.g. a person moves herself from numeric position 1 to numeric position 2; OR is it only impersonal things like the laws of nature or quantum randomness that cause the move from numeric position 1 to numeric position 2? To put it another way, is Vladimir Putin genuinely responsible for the war in Ukraine because he moves at least some of his own body’s numbers (e.g. when he speaks and gives orders to his underlings), OR is the war in Ukraine just an inevitable result of the 13.7 billion-year unfolding of the laws of nature and quantum randomness? What type of world do we live in? Do we live in a participatory world where people are genuinely responsible for their own physical outcomes, or do we live in a sham world with the mere superficial appearance of genuine responsibility?
