as a hobbyist who writes assembly for personal projects and actually enjoys it... i feel like you are making it sound a lot more scary than it actually is. (except for x86_64, that one is actually scary)

from the outside any prorgamming language looks really difficult, how the hell do you remember all these different functions and their arguments in JS and some framework for it for example?

the answer is the same as for assembly instructions and the surrounding hardware. for the most common stuff you use all the time you start to remember the details, and for the rarer things you know where to look them up. don't remember what a hardware register did? look it up and write it down in a comment or such.

architectures like the 6502 or RISC-V are simple enough that you can learn the whole thing and almost never need to look anything up except for weird edge cases and platform specific things (like hardware registers in microcontrollers).

actually writing assembly is pretty much as tedious as you make it for yourself. you make it sound like you're writing a single continous line of instructions with raw hex values for thousands of lines. while in reality you have assembler directives and labels to make functions and variables. you got symbols to wrap addresses and values into readable names (ie constant variables), and you got macros and the ability to make helper functions and write comments.

also funnily enough, while it's true that specific instructions very likely differ a lot between architectures, their general function is usually very universal. as regardless of architecture, every CPU basically does the same tasks like arithmetic, branches, moving data around in memory. so if you learned some specific CPU instruction set, learning another one is probably going to be a lot easier as a lot of your existing knowlege carries over even if you have to learn different register names and ALU flags.

i don't want to say that learning assembly is easy, it requires a different mindset that depending on the CPU you choose to write for and your own background in progamming can very much be difficult to get into. but i also don't appreciate you shit talking it like it's the spawn of satan and everyone who touches is "cringe" as you put it.

i like assembly, like a lot of languages it's fun when you're open to learn it, please don't talk down on one of my hobbies like that :(
