Ellis has some interesting ideas here, but the bottom line is without the earlier "capeshit" there wouldn't be room for whatever Ellis wants to write. He's got a lot of anger directed at something thats a personal preference and not exactly a problem, without offering much a solution in that snippet.
I think most people want to read good comics of whatever variety.
Looking at Manga it's not all super shit, Aside from the obvious My Hero Academia there's variety in a sense and just enough. Even with
Steven Spielberg talking about Superhero movies going the way of the western, Marvel is still on track to dominate the box office, even if the reaction to the Eternals is mixed. People like SuperShit. There's nothing wrong with that. You're not an elite for hating on them.
I'd argue it's gone beyond just enjoying superpowers and bad guys, but the characters that embody that. Look at the fury at any casting announcement or speculation for Wolverine, and there will be pages of discussion, go back to Ben Affleck being announced for Batman, and you will see more than anything, a love for the established characters, and their lore. Not just a love for anyone who can fly and shoot lasers out of their eyes. Henry Cavil's casting remains in doubt and widely speculated on after the black Superman news or whatever is going on with that. It's important to get a character people have been reading since 1938 right. They still buy his comics after all.
Wanting to read 300 good comics even if they wear capes isn't something you need to seek help for. It's that kind of disillusionment that's lead to all the deconstruction we're seeing get popular now, The Boys, Invincible, and Jupiter Rising all successful TV series airing at the same time for example. Those are all pretty good entertainment in one way or the other, and kind of refreshing after a decade of good but unsurprising marvel movies. There's a place for deconstruction and thankfully its turned into a good product in its own right.
The Matrix is Superhero fiction. Even has the dreaded "chosen one" trope everyone should be tired of by now. The Matrix just did it with trench coats and sunglasses, with a little 1337 hacker speak thrown in. It's aged like milk in comparison to Superheroes.
If you don't like Superheroes thats fine, but its not a medical issue, or some kind of fiction faux pau to read or write them. Nor is it a medical emergency. I'd say that level of cynicism is much worse than "Superhero fatigue"
