GPT-4 speaks every human language, knows every programming language, and can answer introductory and sometimes even advanced questions in history, law, biology, and mathematics. In what way is it not more knowledgable than us? Yes, everything there is already known by someone. But look at medicine. Specialists who are able to recognize conditions and recommend treatments better than others make fortunes, sometimes just for briefly looking at patients and answering other doctors' questions. Look at cybersecurity. A lot of exploits come from knowing something the victim didn't about a lot of different pieces of software or processes, chained together. Being able to think through the whole of human knowledge, or even the whole of a single field like biology, is something no human can do. Also, GPT-4 is an existing system, one inconceivable a couple of years ago.
