It seems to have become quite bad with people too. I think it's been overloaded and has too many things to consider now. I tried to get it to guess George VI, and despite telling it he was dead for over 20 years it asked me if he had over 100,000 subscribers or had 'collaborated with Shawn Mendes', this was within the first 15 questions.

It used to almost always know at 20 questions, not it feels like it goes to at least 25 even when it knows the answer
