Not just code. You can plagiarize pretty much any content. Just prompt the model to make it look unique, and that’s it, in 30s you have a whole copy of someone’s else work in a way that cannot easily be identified as plagiarism.
I struggle to find this argument compelling, as it sounds more of a straw man argument than a legitimate complain.
If I write a hash table implementation in C, am I plagiarizing? I did not come up with the algortithm nor the language used for implementation; I "borrowed" ideas from existing knowledge.
Lets say I implemented it after learning the algorithm from GPL code; is ky implementation a new one, or is it derivative?
What if it is from a book?
What about the asm upcodes generated? In some architectures, they are copyrighted, or at least the documentation is considered " intellectual property"; is my C compiler stealing?
Is a hammer or a mallot an obvious creation, or is it stealing from someone else? What about a wheel?
There is still value in quality and craftsmanship. You might not be of that opinion, and you might not know anyone who is, but I do.
