&gt; In this regards, Rust is actually the Blub compared to D and C++.<p>I think this demonstrates a significant weakness in Blub as a concept: there is not even a partial ordering of languages by power. The essay only works because Graham picks the two sides of the debate: Lisp, which Graham believes to be the most powerful of languages, and Blub, a theoretical language that can be stipulated to be less powerful than Lisp in all ways.<p>Outside the essay, &quot;blub&quot; only exists as a slur for a despised language or an insult for another programmer, and it&#x27;s only useful as a way to start arguments.
