You have good perception to see an issue from both sides. I like some automated posts and there will be a point where it will be difficult to tell the difference between a human post and an AI post. Most of the time it is pretty obvious today and the bots are helpful.
As for the comment of following @scholaris.pob, I think you already vote for a wide variety. I am doing pretty well manual curating for most posts of people I know but the problem comes when I look through new posts and can't find anything. I feel like it is a waste of time to even look sometimes. Other times I find new friends. If I did follow then I'm not sure what percent to follow at anyway.
Oh, you don't need to follow my curation trail. There are plenty of people available that can you can vote behind like: @nonsowrites, @aiuna, @wiseagent, @hranhuk to mention just a few.
