Writing is thinking. If you don't spend time writing, then you didn't spend time thinking. LLMs don't think. Consequently, if you outsourced your writing to an LLM the resulting artifact was born of a thoughtless process. Instead of engaging your readers in your thought process you're tricking them with a puzzle. Readers will try to understand what you're thinking about (at least the non-passive ones will). This activity is a dead end for LLM output.
Is writing thinking? Good writing requires thinking but does that also go for sloppy writing? What is thinking? This is the subject of a discussion [1, 2] I'm in - which in true HN style has been greyed-out because of ${reasons} - regarding the question whether these models 'think'. Your comment on writing [being] thinking supports the idea that what these models do is a form of thinking: selecting the next most likely descriptor given the current problem space including all previously added descriptors.
writing is a form of thinking, but there are others
It's not that writing _is_ thinking, but (effective) writing _requires_ thinking. It forces you to take a collection of lose and incoherent thoughts and reify them into an argument that can hold its own weight.
