You're not actually refuting anything — you're just shifting the burden of proof. It's you who should be proving that people in the Middle Ages were stupid and ambitiousless, not me the opposite.
Already did, Byzantine, Karolingian kingdoms, HRE, England, Rome, China,....
Not just did I mention a shit ton of proof I even discredited ur "examples"
And the burden of proof is with u, u demanded a better AI justifying it with them not being ambitious enough to their "real counterpart", which is a statement demanding proof that the AI right now truly is inaccurate
were a time of stagnation, they'd laugh in your face. Of course, the Middle Ages began with a decline after the fall of the Roman Empire, but from that point on, everything was on the rise
It literally wasn't
Every Kindgom and Empire it started with collapsed, technology even degraded even further until the crusaders actually started stealing Arabic/Asien knowledge during the crusades
Best example the Reconquista: As soon as the Christians took over the Muslim regions of Hispania the irrigation systems they had were simply left to degrade and sometimes even outright destroyed on purpose for it being Islamic, the entire advanced agriculture and hygiene through bathhouses was set to zero instead of adapted
just watch any 30–60 minute YouTube video that breaks down the history of any medieval country — Spain or England, for example — and you'll see for yourself that you're wrong about medieval rulers and that they are far from CK3 AI)
That alone tells me that ur entire Normandy point was derived from some video aswell, but guess what: YouTube videos made for an entertaining watch aren't credible nor accurate sources, especially if an entire out of control French kingdom which can't physically defend itself is ignored on purpose to make the video more entertaining and not have it stop after 2min because it can be wrapped up with: The French king had no control over his own army and vassals and thus couldn't do shit against the vikings while the vassals where the vikings landed where torn to pieces because they thought they were smart and "ambitious" in defying their king and kill their possibilities for defence, all while the vikings simply migrated to Normandy not because of some elaborate plan but because the French just couldn't do shit, leading to the last king in that chain of events formally recognizing the vikings as part of them and completely surrendering the region to them
