The point of writing is to convey an idea to another person or yourself at a future date. Authenticity has nothing to do with it. I frankly do not care about the “authentic voice” of the author of a random blog. I want to know if they have any interesting ideas.

I think because so much of an idea is shaped by the language used to convey it, it may be hard to separate the person from the LLM.

I think gp may want to know if a <person> has an interesting idea rather than <person + llm>.

In that case, you can’t achieve that by writing things out by hand. A person could (and many do) use an LLM to generate an idea, then write it in their own voice. Or, they could use an LLM to write out an idea they came up with themselves.

In other words, since the idea generation component can completely independent from the writing component, what you’re asking is not possible in practice.
