That they exist is not the issue. It is the credulity with which people talk about AI agents. AI, no matter the guidelines, cannot be forced to stick to writing things that are real. It is a simulacrum of intelligence, of self directed agency, of humanness. They are sophisticated simulation algorithms. Not true self-aware intelligences.
part of the problem is one of vocabulary. We need new vocabulary to separate what LOOKs like a person with agency, from some that that actually IS a person with agency. By reviling our existing language, we are conferring greater significance with what these programs are doing than is appropriate, based on HOW they work.
it is easy to believe these agents are being truthful and honest, because they parrot real humans, but every AI output I have ever attempted to validate has turned out to be completely disconnected from reality.
