There’s lots of examples going around of generative AI giving bad results but here’s a fun thing you can try at home. Works best if you’re a nobody. Ask ChatGPT (or any similar technology) what it knows about you (based on your first name, last name). In my case ChatGPT decided that my name was just a pseudonym for a famous person with the same last name and asserted that we were the same people.
See how it works for you. Based on the results, you might consider this tech a viable platform for factual information or you might not.
