Honestly all I could say in this comment has already been said by you
1• Bots can cover larger number of people in votes but how do you program a bot to recognize good content
2• Humans can identify quality posts but won’t they die working like a bot someday
3• The best I think In my own knowledge is bringing together AI {Artificial intelligence....the bots} to ease the work of humans afterall that’s the sole aim of AI.
• Final thought
More curators are needed
