There’s a meme going around about artifical intelligence (AI) software actually being plagiarism software, but that’s not really what’s going on.
I’ve used ChatGPT to see what it would do. For topics where there’s a lot of info out there, it’s maybe 80% on point, but genericizes the info, has no particular (or at least no strong) “thesis,” shows no evidence of research, provides no references (and can’t if you ask it to), and is poorly written. So, all of that is similar to a high school or early undergrad essay that would probably get a C or D.
If it directly took sentences from somewhere without citing them, that would be plagiarism/fail/F, but I don’t find that’s usually what it does. It’s more insidious than that.
On more obscure topics (even when the facts are out there in at least a few places), it makes up almost everything and is only maybe 20% accurate, in addition to many of the above problems. That’s not plagiarism, but it’s a definite fail/F.
The program is actually really good at coming up with poems and lyrics in the style of certain writers, but that is also not plagiarism.
