Videogame speed running has this problem solved. Livestream your 10x engineer LLM usage, a git commit annotated with it's prompt per change. Then everyone will see the result.
This doesn't seem like an area of debate. No complicated diagrams required. Just run the experiment and show the result.
The article provides zero measurement, zero examples, zero numbers.
It's pure conjecture with no data or experiment to back it up. Unfortunately conjecture rises to the top on hackernews. A well built study on LLM effectiveness would fall off the front page quickly.
