> This summarizes everything one needs to know

Your comment comes off as very dishonest. How does this quote summarize "everything I need to know". The quote you show appears to be out of context, I followed your link and that it appears to be a conclusion following a number of points explaining why, for the author, Rust's safety feature is apparently not enough to counterbalance it's flaws.

I don't fully agree with the points there (I enjoy Rust), but what does criticizing Rust have to do with "not understanding memory safety"?

Can you elaborate on why somebody has to appreciate Rust? Because I don't see it. Rust is not a religion and we shouldn't treat it as such.
