Very interesting video! Unrelated question: How do you guys think chatGPT will affect the field of psychology? I personally have fun asking the AI a bunch of random questions like “what is consciousness?” “Will the human species survive climate change?” “is human nature good or bad?” Haha speaking about good and evil, I recommend an anime called “Monster”, it’s a psychological thriller and it’s so good. I think you guys would really like it!!! It has one of the best written antagonists in history, in my opinion.
