I'm just learning it, so I'm not (yet, at least ) doing anything awesome with it.

As for why Rust in particular, over the years I've convinced myself that software quality is one of the big ails of, well, anything which concerns itself with the creation of SW. Which is more or less anything these days in technical professions. Strong static typing, memory safety, data race freedom etc. are of course no panacea, but are at least IMHO a step in the right direction.

FWIW, I also think Haskell is totally awesome, but with my background in mostly procedural/OO languages and with small kids at home, I feel I cannot at the moment afford the time to become really productive in a pure lazy functional language in a reasonable time frame. It's on my someday TODO list, though. Oh, and I'm somewhat of a speed freak. So hence Rust.
