Usually, I’m skeptical about new technologies and programming languages. I take every novelty with a pinch of salt. Not because of the steep learning curve and lack of time but because I saw too many examples where promises were not delivered. The majority of the new technologies provided only minor improvements which were not really worth migration time.
When I heard about Rust for the first time, my feelings were the same: if you need strongly typed high-performance native language without GC, why not just modern C++11 (or newer) instead of a new language?
