But it's an interesting observation, don't you think? Why is it that just by adding "... in Rust" you can almost guarantee that people will roll their eyes and think "oh, not another one".
Other languages do not carry such stigma, why does Rust have such reputation?
This is all wild speculation on my part, so please take it with a large grain of salt. I welcome alternative explanations or experiences.
As the OP, this is a big part of it. Rust might be a great language, but people announcing they rewrote grep (for example) in rust doesn't mean they've done anything special. The rust language team did something special. The person making the announcement just took somebody else's idea and reimplemented it for very little reason.
Great! You learnt enough to reinvent the wheel. Now do something useful.
