An agent is an entity acting on someone’s behalf.
You cannot try an AI agent in a court of law, despite the anthropomorphising work the word "agent" is doing.
We say "Google's web crawlers scape web pages." We don't insist you say "Google uses web crawlers to scrape web pages."
We describe software as having agency all the time. It's typical usage and it's efficient and it's well understood.
And we don't get angry when they're used interchangeably.
So yes, I would like to be protected from all parties. I don't think that's nuts.
I agree with you on the liability issue, but I don't think there much question about this issue outside the anti-AI conspiracy campaigns.
And I disagree with your typical usage claim. I myself tend to use the phrase that has the fewest words in all cases. It's like the rule against using passive tense when writing.
The attack here is neither of those things.
