i've learned rust in a month of coding sparsely. in fact, i'm as comfortable today at writing rust as i am at writing go. i've been struggling to learn haskell for over half a year. i think it's an amazing language, don't get me wrong. but the fact that haskell is not harder to learn than any other programming languages is false. after taking a few online course, tutorials and so on, i still believe it's one of the most interesting (if not the most interesting) programming language in existence and also the hardest.
