But OP and Horza's viewpoints are the same strawman argument. The sci-fi premise is that superhuman AIs coexist with humans which are essentially ants.
The correct question is, then what ought to be the best outcome for humans? And a benevolent coexistence where the Culture actually gives humans lots of space and autonomy (contrary their misinformed and wrong view that the Culture takes away human autonomy) is indeed the most optimal solution. It is in fact in this setting that humans nevertheless retain their individual humanity instead of taking some transhumanist next step.
