Oh yes, I remember that you did agree once with the 323 principle, but I forget what
is your problem with the movie-graph/step-8, then. If you find the time, I am please
if you can elaborate. I think Russell too is not yet entirely convinced.
What bothers me about it is that counterfactuals are virtually infinite. So to make
the argument go through I think it implicitly requires a whole 'world';
Not really, as here, you can use Maudlin who showed that the conuterfactuals does not
require physical activity. In MGA, if you give a role to the conuterfactual, you violate
the 323 principle, so that you attribute a functional role in a particular computation
to object having no physical activity for the actual computation.
But I'm not sure about the 323 principle in a QM world.
