There's a lot of excitement about Rust right now. The language has evolved a lot lately and some folks can't wait to get their hands on it. However, it's really important not to rush it and make sure the language is not just what people expect. The language has to reach a point were it's enough features for people to use it and contribute back. It's also important to make sure the language reaches the point where it's possible to keep adding / removing things without much pain.
