Sorry, but chatgpt has no place in serious discussions. You don't know
where its getting its information from or how reliable it is, and you'll
only make yourself look silly by quoting it.

Someone recently asked ChatGPT about me. Apparently I died a few years
ago. This is news to me. However, this illustrates precisely my point
that chatgpt can spew utter rubbish that you've no idea where it's got
it from, and by quoting its output in a serious discussion, you only
make yourself look silly.
