I believe that OP’s point is that “artificial” and “natural” are about how the thing is made. However neither reject that it is actual intelligence. “Simulated” means that it is not that thing. It is like intelligence, and resembles it in some ways, but it isn’t intelligence.
Of course nixpkgs has it. It was added a few years ago, I can’t vouch for if it is up to date or still working.
