I think this has happened before. There are accounts of people who completely lost touch with reality after getting involved with certain scammers, cult-leaders, self-help gurus, “life coaches”, fortune tellers or the like. However, these perpetrators were real people who could only handle a limited number of victims at any given time. Also, they probably had their very specific methods and strategies which wouldn’t work on everybody, not even all the people who might have been the most susceptible. ChatGPT, on the other hand, can do this at scale. Also, it was probably trained from all websites and public utterances of any scammer, self-help author, (wannabe) cult leader, life coach, cryptobro, MLM peddler etc. available, which allows it to generate whatever response works best to keep people “hooked”. In my view, this alone is a cause for concern.
