I believe that the idea for the 50/50 split of HF21 is to get more people to actually curate instead of just selling their voting power to a bot. I know that a lot of steemians either don't want to manually curate, or don't have time for it, but the 50/50 split gives manual curators the opportunity to earn more steem for their curation efforts. It's for that reason that I'm not upset with the coming hardfork.
