I used to have similar thoughts. That said having used Rust for ~1 month now I&#x27;m much father along the line towards drinking the kool-aid.<p>I&#x27;ve yet to see any deal breakers(custom allocators are coming) and I&#x27;ve not yet crashed once(!) in my entire time using it. Try that with C&#x2F;C++&#x2F;ObjC&#x2F;etc. With functional approaches to polymorphism combined with an ownership model that I really like and I think we could see Rust make some serious in-roads in the next few years.
