When, as a retired musician, painter, plumber or electrician, you walk into a project that was done yesterday, you can just understand it and start working. With software (well, frontend mostly), you will have spend an insane amount of work figuring out which billions will of crappy dependencies and myriad of frameworks were chosen and then learn those to start working.
That is just not very normal in most professions.
But sure, you could get bored after doing something for a long time. The getting annoyed and frustrated by not being able to do your job because someone added crap no one asked for (for tech ego etc), making all kinds of pain you have to figure out before writing code, I have not seen outside software dev.
