While true, LLMs are just a more advanced version of it. Let's take Go as example as that is a very boilerplatey language; with claude, I only have to write the meat, for instance;
result, err:= doSomething()
and it'll generate the rest around it. Every time. Faster than I would type it and with more eye for detail (I am lazy, I will forget things as I did it now the 10004th time). So you can imagine some boilerplate scaffold thing that would do this err handling for you, but if you have a custom one, for 'old' tools you would have to tell the tool; now it just does it.
It especially becomes clear in frontend tasks: it just generates 100+ lines of react that work and look good; who likes writing they type of thing manually? I know 0 people who do: after that you will want to tweak it, but the 100k+ lines of react we generally have in a project are not something we would want to write these days from scratch. Which old school scaffold etc tool does that? So that it is 80-90% there for SaaS first shot? I know nothing (doesn't exist) without the lovely verboseness of having to type a million tags?
It saves us a lot of time we don't have to spend on boring stuff. We only have to write the actual business logic and data models; the rest drops out. And of course we only have to write that very loosely, not formally.
