I agree with the parent. Rust is hard because it fundamentally inverts the semantics of pretty much every other programming language on earth by making move semantics the default instead of copying.
Yet there’s no syntax to indicate this. Worse, actual copies are hidden behind a trait that you have no way of knowing whether a particular external lay defined type implements it or not outside of reading documentation. A lot of Rust’s important mechanics are underrepresented syntactically, which makes the language harder to get used to imo. I agree with the parent that in general it’s better for things to be obvious as you’re writing them—if rust had syntax that screamed “you’re moving this thing” or “you’re copying this thing because it implements copy” that’d be a lot easier to get used to than what beginners are currently stuck with which is a cycle of “get used to the invisible semantics by having the compiler yell at you at build time until you’ve drilled it into your head past the years of accumulated contrary models” and oh, as soon as you have to use another language this model becomes useless, so expertise in it does not translate to other domains (though that will hopefully change in the future)
