I’ve read the article again; you are wrong, this is not what this person is doing. They’re using mechanistic interpretability to take our best guess at the ‘state’ of the machine causing pain, and turning that up. Closter to pinching a nerve in something biological.
And you’ve hopped to the defense of someone who says chickens deserve welfare purely because their brain looks kinda like ours, and insist that we can’t use the same reasoning for a chatbot based entirely on “but we have genes in common”. Make a better argument for this defense please so we can talk about that instead of our collectively poor reading comprehension.
