It's not like Rust or Golang will magically save you either. I've been programming for a long time, C is my main language, so that's what I started using at the time and what I'm using still today. We worked a lot on performance and stability, so hopefully it won't suck nevertheless ;-)

Yeah please, let the author know your preferred programming language so he'll rewrite the whole software.

I wasn’t aware that the software had a history behind it, my bad.
