For many, the question is about the code quality as well. Having an AI write substantial chunks of code based on the work of "the average github committer" is being criticized as a problem for security, correctness, and understanding.

I think such arguments are a little overheated, but I do have my copy of tabnine configured to use only local code because depending on the full dataset (which is available over the could only IIRC) seemed like it was going to be more work than it saved.
