I tried to call the US immigration service's info line. It is now staffed exclusively by an AI chatbot (thanks, Elon). I tried a dozen times to get the chatbot to put me on the phone with a human who could confirm what I should do about visits to the US that I took more than 50 years ago, when I was two years old. But the chatbot would only offer to text me a link to the online form, which has no guidance on this subject.
