The history of quantum foundations is soaked in personalities. If David Bohm had held more palatable political convictions, if Hugh Everett hadn’t hated public speaking, if Einstein had had Bohr’s charisma, the story told in this book likely would have been dramatically different. So many of the key events were driven by political or social or interpersonal interactions, not by scientific considerations. This suggests another reason the Copenhagen interpretation is so popular: not because it is somehow better or more suited to the needs of physicists but simply because it was first.
