I played three or four games in all of them the AI players are almost trivial to defeat. In most cases they only have old units or even no units at all. The Germans were leading tech race in last game, even building space port. However their cities had almost no defense and they didn't have one single unit. I only have vanilla civ 6, but this is a disgrace to the series. It simply isn't a challenge to take them out. In none of the games i was ever attacked or challenged by the ai players. What kind of ridiculous difficulty do you have to play this? In all previous civ series king or emperor gave me a satisfying experience and some challenges. And I have never seen that AI players don't build any units. There aren't even a lot of ships around. Usually the AI ships appear on your borders quite early in the game. Nothing like that in civ6. Basically only the Vikings have a couple of (extremely inferior) ships. I am not sure whether that is due to the PS4 port, but Civ 6 is too boring that way.
