Jonathan Perkin's reply when he was asked why he chose to write mktool
in Rust [over C]:
I'm the wrong side of 45. I have zero interest in wasting any time that I might have left writing C from scratch. Writing Rust is pure joy. I can go from an idea to a working, tested, robust, published and packaged implementation in the time it would take me to even begin the first few lines of a C version. The tooling is beautiful, makes programming fun, and the end result usually outperforms the equivalent C. Once it builds I know it will run perfectly on all of the platforms I care about, and I don't have to go around manually testing on them to find all of the various platform and compiler quirks that will break it.
