If software engineering were truly solved, like Anthropic claims, anyone could just vibecode it back. If only they stopped being allergic to the word "open" and open-sourced Claude Code, which, at this point, there is no practical reason not to.

There are numerous copies of the source available for claude code now that it has been leaked. The vast majority of what makes CC useful is already present, and it's unlikely that any killer features will be added going forward.

So it's already possible for someone to "vibecode it back". It's just perhaps not legal.
