First: no one presumed Einstein to be senile. He was sceptical about qm, and being sceptical is good. He also agreed with Bohr that what mattered was results of experiements. That is why they came up with all those brilliant thought-experiements that could only become real experiements much later. Theories that cannot predict anything in the real world might be interesting, but it is not physics. ( I did study at the Niels Bohr institute in Copenhagen a long time ago)
