Oh my, I have a lot of thoughts about this subject!
So, I actually stumbled on the Aesthetics wiki before this episode. I think that some of the weirdly-specific aesthetics are kind of interesting and the baseline concept of the site (A wiki about fashion trends and subcultures) is a potentially worthwhile idea. Unfortunately the major failing of this wiki is the tendency of internet nerds to needlessly subcategorize things.
Adventurecore, Natural Philosophy, Earthcore, Naturecore, Cabincore, Scoutcore, Campcore, Hikecore, Bloomcore, Cryptidcore, Cryptid Academia, Forestpunk, and Plant Mom are all basically just minor variants on "wearing flannel shirts, taking nature walks and listening to indie folk music" (Or "Being the front man of Lord Huron", I guess?) and have basically the same list of associated media for all of them (You can listen to bands other than Florence + The Machine and The Oh Hellos on a nature walk, you know...).
In the interest of simplification, I believe I have boiled down all the styles on this wiki that aren't pre-existing art movements and subcultures into combinations of the following base concepts:
University Nerd Shit
Big tiddy goth gf
It's the 80s: Do a Lot of Coke and Vote for Ronald Reagan
Steampunk is a cancer that is consuming us all
chill lo fi beats to study to, but as a life identity
Seriously, most of it is just vaporwave
I also wanted to highlight this little segment from the entry for "Goblincore":
Goblincore has been criticized of being anti-Semitic. This is because Goblins, especially when depicted as ugly, thieving or greedy creatures obsessed with shiny things, are frequently used as an anti-Semitic caricature. People have suggested alternatives to the name, calling it Gremlincore instead of Goblincore, or simply changing it to Crowcore, Dragoncore, or other aesthetics similar to Goblincore. There are Jewish people who are against Goblincore, but also those who are not.
Goblincore has also been accused of excessively cross-tagging in the Witchblr community, something taken very seriously on the website Tumblr.
Finally, I just want to take a moment to state truth to fact: The only worthwhile vaporwave-derivative is simpsonswave:
