Consider AI NPC comments to avoid annoying repetitions

If I run through the city I always get the same oneliners from NPCs, this gets quickly annoying- at least for me.
I really don’t understand, why no game dev gives more love to the audio environment, this a very important part of the immersion.
And those repetitions of NPC comments are one of the most annoying things in games (at least for me).
So, either give them a bigger pool of oneliners or use AI to get some flavor to the audio envirenment.
