The first issue in my Transgressive Science Fiction series is up (public access, not paywalled):
Hive Minds: Diverse or Totalitarian?
It’s almost by default that a hive mind must be totalitarian, in most works of science fiction. Why? Beehives behave collectively by voting. If neurons over-synchronize, you have an epileptic fit. A spirit of a nation is a more proper comparison. And if it’s to be conscious, it would have to be incredibly diverse.
