This is the key point, I think. I've seen the same as the author: people who want to be writers but rarely read books. And I don't get it.
I recently finished a novel (now shopping around for agents, which was hard enough pre-AI but now...) and reading was integral to writing it. I know good sentences. I know the style of prose I like to read. I know how things can veer between florid and poetic and where the line is. I know how a sentence can be completely different if you read it as though it was spoken, instead of to yourself (some of mine are written to be read.)
I know the things that annoy me: dropping out to put thoughts in italics; descriptions that specify instead of evoke; characters talking without it leading somewhere. (And much more.)
How do I know this? From reading.
And I want to tell the story. It was a story that grew, that I think will anger the right people (it's not too kind to Musk or VCs or the Russian Orthodox Church), and yet is simply an adventure, tumbling our characters from situation to situation like they fell overboard while navigating rapids. Ultimately I wrote a book I wanted to read. It turned out to be about post-apocalyptic startups and sea monsters.
Someday I'll publish, I hope. And no doubt someone will read it and find style they dislike, learn from it things they don't want to do in their writing, either. But I also hope that there are moments in the book that will inspire someone else, in that they too will want to write, based on what they read.
