That's a good question. Many seem to think it's not neutral or decentralized enough and a very few people with the Steem Power get to call all the shots. For now, they may have a point. Will that change in the future? Maybe. Will that make Steem more useful along with the social, community layers on top of it? Possibly. It's also possible the future will see Steem being used in ways we can't currently imagine.
