Steem's future is without rewardpool. DApps like @steem.leo or @sportstalksocial et. al. can take care of their own rewardpool with own distribution models with own leaderships. It will be more decentralized way to distribute token. Steem will be used for SPS, witness rewards and PoS rewards for HODLers. Steem rewardpool inflation is one of the bottleneck for its low price action. People will find DApp front end with their own liking: https://www.steemleo.com/steemleo/@dtrade/future-of-steem-a-full-suite-sdk-for-dapp-developments-and-rc-supply-no-steem-for-rewardpool
