Yes, as I do more rust, I love the fact I can safely parallelise more than I love the memory protection.
Before Rust, I was close to saying that thread-based parallelization was almost impossible to do safely, and was moving to only doing process-level parallelization.
This was actually the reason why Graydon Hoare created Rust BTW. He wasn't looking for a way to get rid of garbage collection or an alternative to C++ (those two characteristics came later from Mozilla, the first versions of Rust had a GC and a heavy runtime with green threads and all), but he wanted a language that helped using all cores on the machine without the traditional issues of shared-memory multithreading.
