Err, out of abundance of caution, the misspelling of "ChatGPT" which I [sic]'d is original to the Texas A&M professor, who repeated the misspelling multiple times in his email/rant. The HN poster quoted the professor literally, and I am thus transitively [sic]'ing the professor – not the HN poster. I am not mocking an HN poster's typo.
That's interesting. Unlike Reddit, maintaining an article's actual title isn't a priority on this site, and moderation is only too happy to change it at their whims. I'm surprised that the spelling wasn't corrected by mods out of pedantry.
