Yeah, that’s a very generous way of putting it but sure, I think that’s valid. My thing was that I don’t believe the aliens have literally any purpose except for being untermenschen, and so if the author has no interest in them then they are superfluous to the real underlying idea (how cool life, especially intelligent life, is) and it makes more sense to express that idea using very different tools. In the story you shared, there’s literally only one short passage that shows even a slight bit of interest in the perspective of an alien, that being:

I rolled my right small arm. Twisted it. Flexed it side by side and up and down. It would be weird not being able to move my body whichever way I desired. These creatures had to move stilted like puppets as well.

Though granted it’s just a bad story overall. But at least if you look at the hype trying to be drawn up in some other stories and even quotes in this thread, there are things that are things worthy of interest and it just gets completely warped by this framing that humans can’t just be interesting, they need to be superior to something that isn’t intelligent enough to flake rocks but is intelligent enough to have lengthy monologues about how superior humans are, so we can get this wank of fearful awe. There’s no such thing as something being great in itself, only being great by brutally subjugating an inferior other. Personally, if I didn’t give a shit about aliens, then I wouldn’t put them in my story and I’d just talk about terrestrial life, because I don’t think you need to dominate something else to be worthwhile!
