The cognitive benefit of writing comes from externalizing and evaluating ideas under friction. LLM conversation provides more friction per unit time than solo drafting because you're constantly reacting to a semi-competent interlocutor who gets it almost-right in ways that force you to articulate exactly where it went wrong.

I checked my logs and I write 10 words in chat for 1 word in LLM output for final text. So it's clearly not making me type less. I used to type about 10K words per month now I type 50-100K words per month (LLM chat is the difference).

The surplus capacity provided by LLMs got reinvested immediately in scope and depth expansion. I did not get to spend 10x less time writing.
