They're using fancy words that amount to capitalist realism + analogies around climate change and other forms of overextractive collapse.

I find these kinds of ideas very boring because they amount to a breathtaking lack of imagination. Really, they're saying, "what if every other form of potential intelligent life is just like us?", right down to the use of cities on planets and an infinite growth model for a global society. Cool, great, that's what sci-fi is useful for, you can critique our society from within another one. But as a group trying to be very serious and use the big words...
