BTW I think some anti-Rust people are more annoying than the worst Rust evangelists - seen some of them calling people not using Rust as “murderers”, because “memory leakage can kill at the right time” - but that’s due to them being evangelists to right-wing politics.
Rust is often treated like it has a split between mutable and immutable state, but it’s really a split between unique and shared state. Shared state can be mutated if certain invariants are held, which types that provide “interior mutability” as its called enforce.
