It's entirely reasonable to have trouble getting to grips with Rust, as ownership and borrowing are quite different paradigms compared to the usual mainstream languages that people tend to know. But there's no way to write "50k lines" of Rust without saying that you understand the language, so I'm baffled by what the author is trying to imply there. If you don't understand the language, then you won't even make it to 1k lines.

I didn't find anything tricky about the ownership model. The last two languages I learned were Clojure then Elixir, both of which had far more concepts novel to me (with no experience in Lisps nor functional languages), yet neither gave me the trouble Rust has.

Frankly your response is typical of the smugness I find with Rust advocates. You 'know' Rust isn't complex (perhaps because of your own experience). When people say they find it so, you consider it your role to inform them about how they are mistaken about their own experience.
