I would point out that most products are useless, and either fail or replace other products which weren't any worse. None of which prevented me from cashing my paychecks for the first half of my career when I worked in private industry.

Most scientific research represents about the same amount of improvement over the state of the art as the shitty web app or whatever that you're working on right now. It's not zero, but very few are going to be groundbreaking. And since the rules are that we all have to publish papers[*], the scientific literature (at least in my field, CS) looks less like a carefully curated library of works by geniuses, and more like an Amazon or Etsy marketplace of ideas, where most are crappy.

[* just like software engineers have to write code, even if the product ends up being shitty or ultimately gets canceled]

Neither of us are going to be changing how the system works, so my advice is to deal with it.
