boilerplate that should be abstracted away in some functions rather than inserted into your code base
Boilerplate is often tedious to write and just as often easy to read. Abstraction puts more cognitive load on the developer and sometimes this is not worth the impact on legibility.
Totally agree - LLMs remove the tedium of writing boilerplate code, which is often a better practice than abstracted code. But it takes years to experience to know what that's the case.
Say I'm faced with a choice right now -- repeat the same line twice with 2 minor differences which gets checked by IDE immediately, or create a code generator that generates all 3 lines which may not work well with the IDE and the build system which leads to more mistakes?
