AI is already everywhere, you are not going to stop it, and then removing the rewards would also chase away most actual humans that are participating. There would really be no incentive at all at that point to continue creating on Hive.

AI isn't near the level now that it will be in 3-5 years. It will be on par with the best human writers in the world. The incentive to post with AI is directly proportional to the rewards you will receive.
