For an episode whose argument hinged on genetic engineering being a cultural practice for the Ilyrians it is strange they never actually had anybody testify as to what significance it has in Ilyrian culture. Or how it is done and why.
If the genetic engineering is done to adapt to their inhospitable atmosphere why are they doing it to every child? They could just edit the germline once and be done with it.
Altogether it felt like the writers just got very attached to the idea of genetically modified individuals as a metaphor for real world marginalized groups that they lost track both of the in-universe practicalities of the metaphor and the real world implications for the metaphor. This was just outright sympathetic to eugenicists, an ideology that has led to the deaths of millions of marginalized people.
