...Except that Rust is thread-safe, so expressing your algorithm in terms that the borrow checker accepts makes safe parallelism possible, as shown in the example using Rayon to trivially parallelize an operation. This is the whole point of Rust, and to say that C and C++ fail at thread-safety would be the understatement of the century.

Memory safe doesn't imply memory efficient and reasonable. Wrapping everything in Arc is the opposite of simple & easy.

If you're writing C code that shares memory between threads without some sort of synchronization primitive, then as your doctor I'm afraid I'm going to have to ask you to sit down, because I have some very bad news for you.

I'm good, thanks.
