Curators are barely humans. Much curation is on auto. Soon AI Robots and Machine/Deep Learning will take over that. The algo on YouTube is already doing this.
Humans or Robots will buy Steem. Or anyone else that is interested. Hell I buy up all cheap Steem. I want more. It's the good stuff and the future. STEEM can't drop to Zero since I will buy all cheap STEEM. Same as Bitcoin can't drop to 0. I will buy. I'm not the only one that would buy cheap and sell high.
50/50 is not fair. Who did most work? The content creator. So you want to leech from them. That would be an unfair deal.
