That's a cloud problem, not an AI problem. I wouldn't trust a game that has a simple login or chat online to be maintained through the ages by any big corp.
If the AI runs locally, especially with all the CPUs with NPUs comming, then that's not an issue anymore.
I would like to see more clever uses of AI in games. One simple example that could sidestep an ethical issue is to hire voice actors to do the main story lines, and pay them extra for the rights to have their voices simulated by AI for random encounters, small NPC comments, even on procedural quests.
Put AI on single-player competitive games, real-time content generation and destruction, storylines and dialogue, even cutscenes. Remain moral and ethical, keep everything local, and be creative. That is all.
