Agree, but to an even further degree.

At one point there were issues with LLMs regurgitating licensed code verbatim. I have no doubt that Claude could parrot a large portion of GCC given correct prompting.

Being able to memorize the various C compiler implementations, alongside the sum of human knowledge, is an incredible feat. However, this is in a distinctly different domain to what a human does when writing a clean-room compiler implementation in the absence of near perfect recall of all C compiler implementations. The way that Claude solved this is probably something a human can't do, the way a human would solve this is definitely something Claude can't do.
