As an experiment, I just asked ChatGPT to "Please identify the open source projects that contain the following code" and pasted the sample from the article. Sure enough, it pointed me at the SuiteSparse library, which is correct (but not exactly where ChatGPT thinks it is). This means Codeium (and others) could theoretically use AI to identify possible attributions that should be included in a project.

Of course, if someone figures out an algorithm that does that, people could use the same algorithm to identify missing attributions and plagiarism in other projects and throw lawsuits around. (Sigh)
