My problem is LLMs making statements on people's behalf as if they represent the position of that person.
Your example of my writing there isn't LLM generated. Did you get caught out by the em-dash? That's thanks to this 10+ year old string replacement: https://github.com/simonw/simonwillisonblog/blob/b8066f870a9...
The only LLM writing on my blog is from when VS Code or Apple Notes occasionally help complete a sentence for me.
