Nonlocality at detection and conservation of energy. Was Einstein   looking for an "epistemic" interpretation, a "superdeterministic" one, or   both?
  In the Solvay conference (1927) Einstein argued against the quantum nonlocal decision at detection on the basis of a simple single-particle experiment, but thereafter he withdrew towards the more complicated 2-particle EPR argument. It has been claimed that Einstein was seeking for an "epistemic interpretation". In the light of a recent experiment I argue that Einstein missed an important point: One cannot have conservation of energy without nonlocality at detection. This experiment refutes also straightforwardly "epistemic" and "ontic" alternatives to quantum theory, and shows that Einstein's "epistemicism" entails "superdeterminism".
