I think bots are good for steemit. Here is my reasoning.

• My thoughts on the controversy over upvote bots
• A Far-Fetched Prediction
• Maslow's Hierarchy of Needs and The SteemBot Revolution
• On SteemBots and Voting Errors

They'll make mistakes along the way, but in the end they'll work through competition and collaboration to rank steemit pages just as accurately as any of the major search engines. Would you ask Google to replace their computing farm with an army of humans reading through every web page on the Internet?
