Graydon Hoare is the creator of Rust.

So of course he likes Rust. And of course his blog post is going to be comparing Fil-C to Rust. Anyone can write a blog post evaluating Fil-C, but only Graydon can compare it to his own design choices and motivations when he attempted to solve a similar problem. That's the whole thing that makes this post interesting.

Makes sense. Now I understand why this post is remarkable, rather than just another "Nice try but I think Rust does everything better" advertisement.
