With the meta point I didn't think AI would be the one figuring out the meta, I seriously doubt AI could be that intelligent.

I imagined a scenario where the veteran/hard-core crowd of any game community figures out the meta but AI consumes the steps of how we end up in such a meta and then spits out that information to the average gamer so they could follow the steps into the meta. It would affect communities because there would be less of a reason for the average gamer to partake in a community but I doubt it would be some sort of a death knell for communities or game development.
