> The bigger criticism of Von Neumann is that he set back quantum mechanics for a few decades: https://twitter.com/orzelc/status/1446414513465696256 https://twitter.com/orzelc/status/1446414513465696256 Really skeptical of this. Not only did he write a famous "little book" on QM (which is still readable to this day), but hidden variable theories are pretty much disproved in QM. So even if he was wrong about the theorem, he was still right about the principle. There's a wikipedia on it here. https://en.wikipedia.org/wiki/Hidden-variable_theory https://en.wikipedia.org/wiki/Hidden-variable_theory I spent a long time studying QM and never heard of anyone taking hidden-variable theories seriously so I don't know what this tweet is about.
