I believe https://news.ycombinator.com/item?id=23715759 works as a response to your point. In my eyes syntax is the least interesting thing of any language, their semantics are way more important, and quite a bit of syntax ends up being derived from it, and the rest boils down to aesthetics. The syntactic complexity that Rust has is there because it is encoding a lot of information, modulo things like "braces vs whitespace blocks" and "<> vs []" which, again, come down purely to style. Also, having a verbose grammar is useful for tools like the compiler and IDEs because having lots of landmarks in your code aids on error recovery and gleaning intent from not-yet-valid code.
