Can you show me an example of a time that you prompted an LLM to provide some code, it did so, and then you were able to track down an original source for the output?
Granted, I've only asked it about some of the weirdly specific technological niche that my code inhabits.
Maybe you should experiment a little more. I think you will quickly learn that your previous impression is wrong. The days of them being merely some sort of jumped up autocomplete are years gone.
It is not thinking. It cannot think. It cannot create.
