Let's face reality: if the devs could have fixed Civ 6's AI, they would have done so already. But they can't. So they're leaving it to modders to do their jobs for them. I'm autoplaying Civ 5 Vox Populi at the moment. The AI is amazing. The AI is exploring, expanding, exploiting, and exterminating. The AI attacks and retreats when it should. The AI builds navies and uses them to bomb, harass, and blockade. Last but certainly not least, the AI builds air units AND USES THEM. To great effect. Bombing and strafing. It's all there and the AI does it. The reality is the devs don't have anyone at the moment who can fix Civ 6's AI (or unit sound clipping effects). Maybe they will hire a coder who can one day if they deem this issue important enough. But I don't think they will (or else they would have done it already).
