# Quote of the Week

> I’ve just realized that “guarantees memory safety in the presence of bugs” is a nice way to describe Rust to C/C++ folks
> Rust is more restrictive, indeed. But only in the sense that a car with seatbelts is more restrictive than one without: both reach the same top speed, but only one of them will save you in a bad day 😊
