I haven't seen it so I'm basing this purely on the discussion here, but like a PP, I don't quite understand the premise. If everyone could have babies (so they can do sperm/eggs?) then why would they have anything like a concept of male or female?
That’s what I don’t get. And because there’s only of these aliens in the show we have absolutely no idea how their society is organised.
There was a 70s episode called The Robits of Death which was set on a mining vehicle. We never actually saw their home planet but we saw enough of their culture to see that it was egalitarian as regard to sex and race - but built entirely on exploitation of robots.
That’s what makes science fiction interesting: not the gadgets and fancy ideas but how those gadgets and fancy ideas shape society.
This episode had the fancy idea but didn’t explore how it would shake society.
