There is a lot of unknown or incomplete data about the cause of the "Definitive" AI ban. Besides the widespread public rejection, what other reasons there may be that are little or nothing discussed. Did alien civilisations have something to do with it? (perhaps out of fear that they could take control without humanity knowing it) Was it a Messer mandate that ended up becoming part of human culture and political structure? Perhaps there are more disturbing causes that remain hidden somewhere far away in the verse? And how much is it estimated that the absence of AI has affected humanity's social and technological evolution?
