I very rarely see AI building an effective military force in the late game. I've played 100+ hours now and I play only on deity. Here are my notions of late game warfare so far: -I have never seen AI build one single aircraft. -I have never seen AI build anti-air units. -I have never seen AI attack with late game naval units -I have never seen AI use a nuclear device. -I have ONCE seen AI build a tank unit (in this case it was actually a modern armor) What the AI does is simply just spam mech infantry (which are strong of course) but nothing else. Air and sea are pretty much for the human player to exploit however much they like. And those who say air and sea are not that useful in Civ VI, well I guess you haven't used stealth bombers and 4-range missile cruisers then.. Or nuclear subs which in fact are able to shoot land targets as well as sea targets. Do you share my experience? Have you seen AI actually building a credible military in the late game? I find it strange how AI plays the late game because early in the game they are very much up to date militarily.
