"And the reality is that there are no absolute guarantees. Ever. The "Rust is safe" is not some kind of absolute guarantee of code safety. Never has been. Anybody who believes that should probably re-take their kindergarten year, and stop believing in the Easter bunny and Santa Claus."
I didn't claim that Rust provides absolute guarantees. I don't know anyone who has claimed that. The only place I've heard that being claimed is people saying it's commonly claimed so by Rust advocates.
Even in my comment I quoted a passage that said "we don’t expect that number to stay zero forever". This is important. Although it has been successful so far, there will be bugs in it, even the odd memory safety bug.
That's still progress! Fewer bugs than before is progress, (mostly) eliminating a class of bugs is progress. I only addressed a person who was saying "there will still be some bugs, so there's no point tackling this at a language level". They're unable to grasp the idea of progress.
