> it seems like nearly every tech opinion piece I read now boils down to "things used to be hard but they aren't anymore because LLMs can understand things faster than we can, so can ignore/change fundamentals!"

Sure, LLM coding agents being capable doesn't mean we can ignore fundamentals.

But LLM coding agents surely adjust the cost/benefit considerations for all kinds of programming efforts.

Arranging your code in such a way that it's so complicated you need an LLM to understand it is surely silly.

Using an LLM to write a macro because you weren't going to learn how to write macros and deal with all the subtle cases? I think that's arguable.
