Love the sentiment, I think rather than new labnguages I would like to see forms of obfuscation that cannot be reversed and maybe encryption.
Also I been thinking about how we can (re?)create offline open source or fully obfuscated OSS online that has some kind of tooling to prevent exposure to training.
It would be interesting if there was a metaphor we all understand but we could repurpose for this. Undoubtedly new CPUs would need to be made.
