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.
