What about
_The Cellular Automaton Interpretation of Quantum Mechanics_

What about it? Gerard t Hooft is a fan of superdeterminism, it says
that out of the infinite number of ways the initial conditions of the
universe could have been in it was actually in the only one where
things were so hyper precisely arranged 13.8 billion years ago that
today we always make exactly precisely the wrong choice whenever we
set up our experiments, so we always end up getting fooled and think
some things are not deterministic when they really are. That's a lot
to swallow. I'm comfortable with the universe being indifferent to us
but if superdeterminism is true then it's downright sadistic; although
if true we must be mighty damn important if something went to the
trouble of setting up the entire universe in the only way that would
make fools of beings that would live on a average planet orbiting a
average star in a average galaxy in 13.8 billion years.
't Hooft makes the point that determinism implies superdeterminism. If
we start with a set of low entropy initial states that could have
represented he universe shortly after the Big Bang, then billions of
years later some of these initial states will have evolved into ones
containing human physicist doing experiments. If we then take one such
state where Alice does a measurement with a certain polarizer setting,
and we consider the inverse time evolution of the counterfactual state
where Alice choose a different setting but everything else is kept the
same, then you won't get to a valid low entropy initial state. 't Hooft
argues that this objection makes the counterfactual reasoning in Bell's
theorems invalid.
