Just wacky I had to scroll this far to see Go mentioned. In certain contexts Rust is very impressive, in others Go is a much better choice. I'm really starting to hope that we'll see some of the important advancements in Rust packaged up in a better language.
These one-liners aren't super-constructive, my own comment was hardly in-depth, so whatever...
On any team or in a community your most likely to have a range of skill levels across members. A language can be many things, a powerful tool or a strong barrier.
When I first heard about Rust I thought we were on the verge of getting some real advancements across a much larger community of developers and scope of projects. Instead I think we're headed further down a path of at least 3 major groups of PL (scripting, memory-managed, precise semantics). Who knows, maybe it's for the best. If so we better get busy improving the inter-op.
