This is either brilliant or scary: Anthropic accidentally leaked the TS source code of Claude Code (which is closed source). Repos sharing the source are taken down with DMCA. BUT this repo rewrote the code using Python, and so it violates no copyright & cannot be taken down!

The repo: https://github.com/instructkr/claude-code… The brilliance: copyright does not protect derived works. Rewriting TypeScript code in Python means copyright no longer applies. The scary thing: it can be done in trivial amount of time, with AI agents. This one was done with Codex. This can be done not just for this specific codebase, but any codebase. So what happens with copyright? Will it evolve with AI, or be stuck pre-AI?

You can imagine Anthropic being in a pickle: 1. Do they just leave this, and look the other way, ignoring that it's not exactly fair to transform their code and leave it up there 2. Do they claim copyright applies... but this could be bad for their own business in much bigger ways: eg imagine regulation coming into play that bans this. Claude Code and other tools would have to refuse this kind of generation. Lawsuits against AI labs could spike etc So my bet is #1 happens. Not the interest of an AI lab to expand copyright protections to derived work cretated by an LLM...

Worth asking btw if code fully written with AI has copyright protection? Anthropic is big in saying most of Claude Code is generated by AI. Not 100%, but close, and the last few months pretty much all. Another interesting copyright question.
