Being able to write code that compiled into assembly, instead of directly writing assembly, meant you could do more. Which soon meant you had to do more, because now everyone was expecting it.
The internet meant you could take advantage of open source to build more complex software. Now, you have to.
Cloud meant you could orchestrate complicated apps. Now you can't not know how it works.
LLMs will be the same. At the moment people are still mostly playing with it, but pretty soon it will be "hey why are you writing our REST API consumer by hand? LLM can do that for you!"
And they won't be wrong, if you can get the lower level components of a system done easily by LLM, you need to be looking at a higher level.
