Complaining about the "LLM voice" is a bit like complaining about the compiler error "voice". I configure my coding LLMs to get to the point and be succinct.

It's a computer giving me information, so as long as the communication is clear and efficient, who cares about particular word choices?

It's hard to interact with a particular dialect day in and out without it eventually seeping into your habits of speech and thought. So the people most likely to care are your friends and family once they get bored of hearing about the "key insights" you've been having all day.

I care about particular word choices when no matter what I do it won’t obey me and stop using them.

I care about the “AI voice” only when I’m forced to deal with it when all I want is for Claude to stop spinning up long prose and referring to itself as a person just to maintain Anthropic’s “behave like a human” design with no way to make it fucking stop.
