A team of three people including me have used Rust _daily_ for almost a year now for at Chain[1]. Rust is _by far_ much easier to use than C or C++ and lets us get things done with clear design, record-breaking performance[2] and utmost safety[3]. Basically, people who avoided C/C++ for years as unsafe, lacking usable abstractions and generally hard to use, switch to Rust and enjoy it.
