Maybe for more complex games, example: economics. But chess is pretty simple compared to seven billion people going their own ways.

On the other side, AlphaZero and all the previous Deep Mind's AIs played some very different go than human players did. Every single move was not unheard of but they were dismissed by human masters as not good. The most noticeable contribution was the total change of how to play corner invasions. By looking at game records we can draw a line between pre and post AlphaGo. Maybe go is a little bit more wide than chess and AIs have more space to find novel plays.
