No, I did some web searches (with Duck Duck Go) which came up with
pages including some on Wikipedia with key information that didn't
have references. From those I reached the above conclusion, but I
won't believe some AI guessing from the same sources any more than
what I concluded myself (indeed much less given the BS answers I've
had while testing one of those chatbots out). I'm hoping for some
human input, ideally based on broader experience than the top
search results.
