I'm not a rust user, but I would argue you are still managing memory manually, you're just doing a lot of it through rust's type system, which can check for errors at compile time, rather than through runtime APIs like the C or C++ standard library. The question then becomes whether it is easier to manage memory through Rust's type system versus via standard runtime APIs.

From what I've read, Rust memory management actually requires more work but provides fantastic safety guarantees. This could mean that rust actually lowers productivity at first, but as the complexity of the code base grows, some of that productivity is restored or even supercedes C/C++ because you spend no time chasing runtime memory bugs.

For some products or projects, the costs of shipping a security flaw caused by a memory bug exploit could be high enough that a drop in productivity from Rust relative to C is still more than justified due to external costs that Rust mitigates.
