The programmers who live in Flatland

A sadly typical flavor of essay: a lisp enthusiast who believes that learning lisp has made them into a uniquely Very Smart Boy who can think thoughts denied from programmers who use other languages. The "blub" paper asserts that there exists a linear hierarchy of goodness and expressiveness in languages, where lisp, by virtue of its shapelessness, exemplifies the pinnacle of expressiveness.

This is a profound misapprehension of the nature of language design. Languages exist within contexts, and embody tradeoffs. It is possible- common, even- to fully grasp the capabilities of a language like lisp and still find it inappropriate or undesirable for a given task. Pick any given context- safety-critical medical applications, constrained programming for microcontrollers or GPUs, livecoding environments where saving keystrokes is king- and you can find specialized languages with novel tools, execution models, and affordances. Perhaps it never crossed Paul Graham's mind that lisp itself might be a "blub" to others, in other situations.

The idea of a linear hierarchy in languages is the true flatlander mindset.

It would also be a lot more persuasive if the article provided even a single example of how Lisp enables superior solutions.

Instead, it's just an ad-hominem attack based on the idea that non-Lisp programmers are too limited in their thinking to appreciate Lisp.

Show me a convincing example of something that's simple/clear/elegant/superior in Lisp, and how difficult/complicated/ugly/impossible it would be to do the same thing in Java/C++/Ruby/Python.

In the absence of that, the entire article can be refuted by quoting The Big Lebowski: "Yeah, well, you know, that's just, like, your opinion, man."
