It has nothing to do with intelligence. I can grab an average teenager without any kind of programming experience, and teach him enough in one day (maybe 2), for him to google, and copy paste him a working site with some interactive elements. Sure it will have a ton of bugs, probably only work on his browser, but it will work. For programming in rust, you need to have at least basic understanding of hardware model and operating systems, know concepts such as stack/heap, references/pointers etc. Its a ton of additional stuff you need to know, before you can even start. None of that is particularly hard (well most of it). But it's a lot of it. There are productive JS fronted developers who wouldn't be able to tell you what event based loop is.
