I used to have similar thoughts. That said having used Rust for ~1 month now I'm much father along the line towards drinking the kool-aid. I've yet to see any deal breakers(custom allocators are coming) and I've not yet crashed once(!) in my entire time using it. Try that with C/C++/ObjC/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.
