“ double (a) variables only take value at discrete interactions and (b) the value a variable takes is only relative to the (other) system affected by the interaction.” Layperson here. Can I read this as saying yes to locality, no to realism, and violation of causality since this only depends on who measured it, another interaction could interpret cause and effect differently?
