In this talk I will go through the latest developments on the local-realistic nature of quantum theory by Deutsch-Hayden (2000) and Brassard-Robichaud (2017) and criticized by Wallace-Timpson (2007). I will comment the connections of the proposed view with the principles of locality, the Leibnitz principle, the existence of local inaccessible information and the necessity to take into account the counterfactual properties of physical systems. The recent developments to the Deutsch-Hayden picture that will be mentioned are the expansion of the formalism to include fermionic systems and to describe the Everett many-worlds interpretation.
