This title is more click-bait than I would prefer. It's not as much about becoming a better writer per se as becoming a better writer for Medium or some blog post. No long paragraphs? Use ChatGPT for editing? Lots of white space? One idea per paragraph? That has little relation to memoir, fiction, academic writing, or most forms of writing other than Medium-like "content" quick posts.
Drafting and clarity are relevant to all forms of writing, however. It's bold to claim to be a writing coach and then put out a piece that blurs more universal advice with very genre-specific advice with making a distinction!
