It’s a cool take, and it’s interesting that multiple medias (tv, videogames, books, etc) have fantasized/theorized/explored multiple ways regarding that, in all 3 great filters.
Star Trek for one, goes into the “universe is full of different people” (and ignoring the reasoning given for most of species looking like humans is that we all have one common ancestor that sew their seeds everywhere, which in my opinion feels like it’s a post concept to explain our regular human actors cosplaying other races without spending much in 3D lol) and you could say that each planet had it’s own Great Filter (#1) as each has it’s dominant civilization, and now the human space exploration is just tying these different civilizations together (being space-nosy) bringing every planet into an entire space’s great filter situation (which could be the Borg assimilating everyone - filter #3, etc).
The great filter #1 and also #3 “Almost no life makes it to this point” has been beautifully explored in the MMORPG Final Fantasy XIV, in the Endwalker expansion (spoilers ahead lol):
The thriving ancient civilization of eos ago (of the planet your character is from) had powers to create anything at will had as one of their citizens, a guy curious about the possibility of other civilizations elsewhere, created sentient “probes” (Meteion and her sisters) that were sent across space in order to find other civilizations. What each found was pretty much the great filter #1 happened AKA there were other civilizations in different planets BUT with a mix/caveat that all of them had already been past a second Great Filter of sorts, which exterminated all of them.
The “Ultima Thule” region explores 4 civilizations (Dragons, Ea, Omicrons, one necropolis there’s no actual name of the race, from what I remember) and the dungeon “The Dead Ends” explores this too, with the “probe” showing us players 3 of such other civilizations, all of them in different civilization levels, but that shows that each civilization had went past the filter #1, into their bigger filter:
- A blue, mostly water planet, fell into pestilence and started rotting inside out. And the people started blaming the people who fell ill rather than the illness/curse (that disfigured and made them die and/or become a monstrosity), and the extermination of the race itself happened.
- A brilliant planet, who managed to eradicate all diseases, before starting to eradicate all lives that have been saved by *- and I feel it was a pinch at USA) - * trying “greater freedoms”, buying peace with “fire and steel” (aka war and conflict) until every single person died. It was even poetic since when someone asked “What’s the point?”, there was noone else to answer as they were the last one alive
- There was a planet without any conflict whatsoever, but also no other issues or joys, to the point they all became apathetic to everything and even life. So they created a creature to “release” them from this world, so their only joy was to wait for said creature to come and die. Until all died.
In the narrative, seeing so many of said planets going through different filters but all of them ending in death made the “probes” kinda just assume everything in the entire universe boils down to pain, suffering and death… And they started attacking the ancient guy’s civilization because there’s nothing else to be had.
It’s pretty cool reading about these Great Filters after experiencing the game’s expansion years ago, I can totally see how the filter theory can apply to these different fantasy/fiction civilizations and how they could be used as theory examples for our IRL predictment of “where are the other civilizations”.
