Superdeterminism could reconcile quantum and relativity

From this layman's emotional point of view I never really liked "many worlds" and that sort of thing. I'd be quite accepting if the answer turns out to be super-determinism.

The impact that apparent world branching has to domain of the free will question is purely due to the "amplification effects" that a complex control system like our brain can have in reaction to something perceived as a "measurement" result.

We cannot sense a superposition state directly. The moment we probe a particle, our instruments and us (the environment) becomes entangled with the observed particle. The instrument and later we the observers of the instrument are ourselves a quantum system with a well defined quantum stats, and a third observer not yet entangled with us can treat as still in a superposition state.

The idea is that everything evolves according to the Schrodinger equation. The wave function never really collapses. The illusion of wave function collapse springs out of the way that a control system like a brain or a mechanical automaton processes it's inputs while being in an entangled state with the thing they observe and thus react to it's state differently in the different superimposed states. This difference becomes amplified. A control system like a brain is not necessary; just pure macroscopic environments are enough to diverge the apparent state of the systems so that it's useful to think in terms of "world splitting"; but it's just a useful fiction; very useful because that's all we'll ever witness.

The amplification effect of control systems makes it easy to concoct extreme thought experiments. Let's imagine that spin up means you fire off a rocket and go to Mars and spin down means you stay put. All we did is that we managed to amplify the effect of this single superimposed state of one particle, into a macroscopic superposition of a rocket being on earth or on mars

Also, your examples are not entirely accurate. It has been repeatedly demonstrated that zapping a part of the brain cannot consistently override the will, and the correlation to, for example, the motion of a limb to the activity of the brain does not stay consistent, but disappears after multiple attempts when the subject under experimentation resists. That doesn't prove that the will is independent from the brain, but so far, no one has found where the will expresses itself in the brain. Right now it is just taken on faith that it does so somehow.

And then there is perception. We can find general correlations for areas of the brain that respond to shape, color, smell, and kinesthetic sense, but nowhere where the various senses are assimilated and correlated into a cohesive perception.

We can alter mood, and induce hallucinations, but again, have no model as to how either translates to perception and self-awareness.

Before we can determine whether the will is free, we first need to define what the will and perception and self-awareness even is, and how it arises. And we don't have a clue where to start.
