'unsafe language' sounds like something out of '1984' or 'Animal Farm'; a totalitarian political euphemism, attempting to demonize all 'others'.
The reality is that no language is actually 'safe', and 'safety' itself is a complex trade-off between enforced restrictions, flexibility, and other factors, just like in life.
Instead of "unsafe", we could use "computer verified correctness" or something similar. Truth is that humans make mistakes and Rust is the only "project" which achieves verified correctness in some critical areas, in projects of any complexity.
Developers gotta have religion. It's not about fear of death like mainstream churches, it's about fear of buffer overflows.
Developers already had a religion, the Church of Emacs. Heretics will not be tolerated.
