Except they don't use AI in WH40K. They use cloned human brains for anything that can't be achieved with basic electronics. I'm pretty sure the AdMech actually consider AI a form of heresy against the Machine God and the Omnissiah.
They do bionically enhance the human brain with Neuralink-style interfaces, and even go as far as entombing a person in a pod of brain fluid to augment their interface to one specific machine. But full on AI is not kosher AFAIK
