What about AI improvements?

Since 1998, I always hated the AI in the game.
When you play against computer opponents, the latter have no strategies at all.
I never saw AI building walls around the city, or building armies of mixed units. Per example, it will send 20 catapults to attack your city, or 10 priests to convert your population.
When you make the AI your allie, it will never fight for you, never help.
The battles look ugly. The units are repeating the same movements.
I would like to see some improvements in the AI after 20 years of development.

You have a point, but didn’t you like the AI of AOE Online? It brought some new game play experiences and much harder AI to beat. I did like that part for sure.
