Even there, I am not sure whether if the AI bcomes too advanced, it will be of interest for many players (you might of course nevertheless be interested):

Here, the relevant comparison is to watching (the past) games of AlphaGo against Go grandmasters, where even the highly qualified commentators had insane difficulties explaining AlphaGo's moves because many of the moves were so different from the strategy of any Go game before. The commentors could just accept and grasp that these highly advanced moves did crush the Go grandmaster opponents.

In my opinion, the "typical" sandbox game player wants to watch something that he still can "somewhat" grasp.
