To them, Rust is rather intimidating I'd argue that Rust's concepts of ownership, borrowing and lifetimes are rather intimidating even to people who have had to think about memory allocation. You can get part of the way there with analogies about stack-allocated vs. heap-allocated in other languages, but ultimately it's just a concept that, say, the average C programmer is going to find alien and difficult at first (largely because it's designed to prevent common types of errors committed by the average C programmer).
