I think what I don't like about the letter is, it is easy to ridicule this, you know, proposal to pause for at least six months with training of AI systems. But regardless, this letter is good and so far as it makes it just pushes forward via the AI safety. And in that case, if someone is trying to make an agent topic AI, that can autonomously do stuff at it once, which is the actual kind of scary thing,. Not a GPT four, which is not autonomous at this point. That is something concrete that probably needs to be established in some form.
