Go sure is easy to get started with, but it would have to be 20 times better than it is to make me give up the JVM.
I like Rust because it gives you control (like C++) but does so carefully (unlike C++). In ten years, Go should be a great alternative to Java and Python. In ten years, Rust should be a solid alternative to C and C++. (That is, assuming they both succeed.)
A language like Rust, which is reasonably expressive and safe but fast and with little overhead, should become a very desirable language as hardware improvements become more marginal (adding more cores eventually brings diminishing returns), and as battery life becomes more important with mobile devices.
But the portability problem is solved really well by the JVM. I'm hoping Rust will make writing cross-platform, native code easier.
