Speculation… 
but I’ve been wondering if more people becoming more comfortable turning to AI as a first port of call would impact communities (especially those with a support element).
I’m tentatively thinking that not only would there be fewer questions being asked of the community, but also fewer opportunities for existing community members to answer them. Less to read also may rattle down to less reason to linger. Plus if there are fewer ‘easy questions’ then it’s harder for newer members to convert from ‘askers’ to ‘answerers’.
Though I have no data to back this up.
