Comment on "Why interference phenomena do not capture the essence of quantum theory"

Abstract: It was recently argued by Catani et al that it is possible to reproduce the phenomenology of quantum interference classically, by the double-slit experiment with a deterministic, local, and classical model (Quantum 7, 1119 (2023)). The stated aim of their argument is to falsify the claim made by Feynman (in his third book of Lectures on Physics) that quantum interference is impossible, absolutely impossible, to explain in any classical way'' and that itcontains the only mystery'' of quantum mechanics. We here want to point out some problems with their argument.
