There is no reason to avoid getting better at writing.

I feel like people often misunderstand that writing isn't just busywork, but rather instrumental for developing a deeper understanding. Formulating a sentence forces you to clear out uncertainties you might have. And writing it down serves as extended working memory.

I can imagine there being some middleground, like not bothering to learn where to place commas and having an LLM insert them for you, but from my biased position of already knowing how to write correctly, I do struggle to come up with scenarios where this actually makes a difference.
If you know how to read, you'll have a sense where commas aid with that. Anything beyond that is just pedantic wankery anyways.
