Nobody here is saying c/c++ or rust is better after their respective learning curves. No need to be defensive, they're just languages, and every language has its strengths and weaknesses.
To the point: modern c++ is easier to learn nowadays. shared_ptr and unique_ptr are as easy as Rc and Box, but without the borrow checker making things harder. One doesn't have to deal with the decades of difficulties when learning c/c++. One can choose to dive into a terrible legacy c++ project just like they can dive into an unsafe mess like Actix, but thats hardly a reflection on how easy to learn a language, just the codebase you're learning from.
And rust's front-loading of problems is a great thing! It also makes it harder to learn, which is the point here.
