How would a fresh graduate be able to write safe C code when even experienced people are unable to? I have worked with multi-threaded C++ code long enough to see that it's impossible to work in a team while keeping the code safe. Usually servers crash and canaries catch it in production, but if we have type system improvements that solve these problem, why not take advantage of it?
