Thanks for your comment @jennsky , I agree that some will use bots, but , I also think most of the Whales are technical, and have the ability to manage the bots and optimise them. Vs. If we have a large middle class, most of them will be ordinary writers like you and me. They will have to currate carefully, and also there will be a lot more middle class than whales, hence more people have a larger influence on what should be trending. Not only one or two people.
