I agree, Paul. (In no small part because I followed your writing on the topic from the beginning.) When GPT 3.5 arrived, I was unimpressed. But when GPT 4 showed up soon after, it blew my socks off. From the start, critics popped up focusing on failure cases and weaknesses. But you, I, and others recognized that a new world had just begun, and would only get better as time went on. I could finally talk to my computer in plain English , and it had correct answers for almost everything every time.
