What I'm looking for

no take a trip to godoc.org and look at the mountain of libraries that have already been written. why? because Go is simple. Rust is not simple. i still hope it is a success, but it still has another year or so until it achieves both a "1.0" label from its own development team, plus enough "batteries included" to make it useful in real projects (i have seen what is available now for libraries...it would not be considered "batteries included" by modern standards)

my guess is Rust may be killed by bad timing. Go is getting huge momentum, people are already running their businesses on it and you can make a living as a full-time Go programmer (i am arguably doing this now and have been for a year). Java8 will de-stupid Java just enough that it won't be worth it for most coders to drop Java in favor of Rust. and now someone will respond by telling me Rust is designed to replace C++, not Java...nonsense. nothing is going to "replace" C++.
