I'm very uncovinced. History showed us very complex systems reverse engineered without access to the source code. With access to the source code, coupled with the rapid iteration of AI, I don't see any real moat here; at best a slight delay.
Source code is one thing; tests covering the codebase are another.
And if you just copy the source code or translate it one-to-one into a new language, rather than make a behavioral copy, there will be copyright issues.
The tests are absolutely essential, otherwise there's no signal to guide the LLM towards correct behavior and hallucinations accumulate until any hope of forward progress collapses.
I have tried to post this here but it has not got traction.
I have a demonstrated process here on my blog (all hand written without AI).

Yes, it is absolutely possible.
