We get so angry at LLMs because we can. Without any social or even emotional repercussions for expressing these emotions. If the models actually acted like people in response, we wouldn’t do it. Some of the people I work with daily make similar mistakes, I don’t find myself yelling at them.
I think this is simply part of the darker side of human nature, when we interact with entities who will take abuse, we tend to deal it out.
I dread people who get abusive with AI, because I know it's only fear that prevents them from being like that with me. Even if only it is the fear of hurting me, it's still terrible because every fear can pass.
