A friend of mine was trying to show me how surprisingly good ChatGPT is, and sent me an example prompt and response that produced working code. Just to check, I entered the prompt into Google and got back the StackOverflow page with verbatim the same complete block of code. It was even the first Google hit. The only thing ChatGPT had done was copy something easily findable on the web and scrub away the attribution, license, and source information.
