And I know much of it is not necessarily the fault of the devs, with management and deadlines preventing them from doing the best possible job, I myself was forced to release half broken updates a few times because of that, but they are not the only problem.

There's a real problem in today's programming culture with thinking that computers are so fast, any garbage code you write will be fast enough, or that you only need to optimize the hot path. Apply that philosophy throughout all your codebase, and suddenly there is no hot path, everything runs like shit. People should also actually learn how things work, not just frameworks, otherwise they won't be able to make informed decisions about what they write.

Also stuff like "Clean Code" and other similarly dogmatic principles still permeate many of the codebases I see. Nigh implementable jungles of <10 lines long functions and OOP garbage that make working with everything a massive pain, other than making every function call virtual and thrashing performance. You need to maintain such a massive amount of context in your head just to figure out the flow of a particular piece of code, with the aid of a debugger because everything is done through abstract classes or interfaces, that even making the smallest change becomes a tedious and error prone task.

Also fuck dynamically typed languages. They suck, every single one of them.
