As a general rule, if an announcement about a movie project is over a year old and nothing else has been mentioned since, you can safely assume it's no longer a thing.
The better question would be: Even if we did have such tools, what stories would be worth telling with them?
I don't doubt that we will eventually have something like this, in the same way we now have CGI with forensic fidelity. The problem will no longer be "How do we realize this?" but "What's worth realizing?" The new limit is no longer technology; it's our taste and our discernment, which are not being developed anywhere nearly as aggressively as our tech.
This looks like it could become an excellent alternative in time to not just NumPy and Numba, but also Cython. I know that may be more ambitious than your original intentions, but that's absolutely what sprung to mind.
