> with modern networking, data speeds and computing capacity, a centrally-planned economy could work. Ludwig von Mises' whole point is that you are working with unknowable inputs, so you can never calculate correctly. This is why a socialist, centrally planned economy can never work. For example, people's preferences are unknowable before a transaction takes place. And, no, surveys don't work because what people say they want and what they actually spend their money on are different things. No amount of computational power can create outputs for unknown and unknowable inputs.
