Well, I am confident that greed hasn't gone away. Several of the bidbot owners have joined the oligarchy of Hive, and I think that was the price of the bidbots going down.
That can't happen with AI. AI displaces people in content creation, and Hive as a community cannot coexist with AI usurping our sovereignty, taking over society.
What we have done to quell excessive automation and financialization on Hive so far has been reactive. We have used downvotes to demonetize fraud. I don't think that can work against AI, because we won't know where to fly those flags.
What we can do is eliminate opportunities for financialization and tailor rewards for human people that fraud isn't interested in.
We'll see.
Agree, we will see, it's still an interesting experiment. :)
