Command economies might work better now that we have the capability to transmit accurate market information in (near) real time.
Chile's Project Cybersyn was coordinating productivity all the way back in the 70s, with Telex machines. Perhaps we can bottle some markets' behavior into computers and good C&C human structures.
should be pointed out that it was coordinating economic activity not in a 'command economy' sense. The project actually aimed to drastically decentralize economic decision making by applying cybernetic principles to factory work. The goal was for local managers to be able to respond to data in real time. De Beer's so called 'cybernetic factory' was even received positively by Hayek, who was not known for being a fan of command economies.
