If you believe that then you haven’t spent much time working in different paradigms of programming languages.
Syntax is the easy stuff to learn. It’s any shifts in paradigms (eg pure functional vs imperative vs logic… etc) that takes time to learn.
And I say this as someone who’s written professional software in well over a dozen different languages. So I understand well the challenges learning something new.
I have written production code in about a dozen languages as well believe it or not.
I have also trained people who were good to decent software engineers in other languages to write rust. The syntax is nontrivial for a lot of people. There are a lot of people who gave up trying to learn rust, especially before the rust book became what it is today.
People typically fight the borrowchecker until it clicks. Learning from an LLM and reading only means you have to be as good as the rust compiler without any experience writing the language. It's got to be way harder that way.
