alt Hacker News100% agreed. Maybe this inner reaction will disappear over the years of being exposed to the GPT writing style, or maybe LLMs will be "smarter" on this regard, and being able to use different styles even by default. But I had the same exact feelings as you reading this piece.
It's really simple to fix by asking an LLM to apply a style from a sample, so my guess is a lot of product will build in style selection, and some provider will add more aggressive rules in their system prompts over time.
