It is 2024, why does the game still not save your settings.

You are a developer. You know things are very rarely simple as it sounds. I can come up with several questions that would need answered before even thinking about starting on automating this.

Yes, there are design issues (like what settings should remain local only?) and technical constraints and limitations specific to this game that we may not be privy of, but I would be surprised if it was anywhere near unsurmountable. I'd be more inclined to believe that it was never done for lack of sufficient priority given to the feature.
