Or perhaps, just perhaps, the true higher-dimensional move is realizing that choice of programming language isn’t usually the critical factor in whether a project, system, or business succeeds or fails, and that obsessing over the One True Way is a trap.

It might surprise the author to learn that there are many people who:

1) Have tried lisp and clojure

2) Liked their elegance and expressiveness

3) Have read through SICP and done most of the exercises

4) Would still choose plain old boring easy-to-read always-second-best Python for 90% of use-cases (and probably Rust for the last 10%) when building a real business in the real world.

The article could really benefit from some steel-manning. Remove the cute Flatland metaphor and it is effectively arguing that lisp/clojure haven’t been universally adopted because most programmers haven’t Seen The Light in some sort of epiphany of parentheses and macros. The truth is more nuanced.

This is me to a T — even when I'm building hobby projects. The point of writing any code, for me, is most of all to see a certain idea to fruition, so I choose what will make me most productive getting where I want to go. And while I still worship at the altar of Common Lisp as an incredibly good language, the language matters much less than the libraries, ecosystem, and documentation for productivity (or even effective DSL style abstraction level!), so eventually I have had to make my peace with Python, TypeScript, and Rust.

The reality of modern software development is that most people focus on languages they use for work, and developers are statistically likely to be employed at companies with large numbers of other developers.

The technical merits of languages just aren't relevant to choosing them for most developers, unless they're helping solve a people problem.

"Artisanal" languages like Lisp, and Forth can be fantastic at solving problems elegantly, but that's not the most important thing to optimize for in big organizations where a large portion of your time is spent reading code written by people you've never met who may not have known what they were doing.

Many of the tools that come from big tech are designed to ease the challenges of organizational scale. Golang enforces uniform styles so that you don't have idiosyncratic teams doing their own things. Bazel is a largely language agnostic build system, with amazing build farm support. Apple and Google have both contributed heavily to sanitizers and standard library hardening in order to detect/eliminate issues without reading the code. Facebook has poured vast resources into automatic static analysis. AWS built an entire organization around treating all their internal interfaces the same as external ones.

Clojure is built on dynamic typing. This is pain. I wrote enough Python (pre-mypy), Javascript, and elisp to say this. Past certain size a dynamically typed codebase becomes needlessly hard to wrangle because of that. Hence the success of Python type annotations and Typescript.

Instead, the world should have seen the light of Hindley-Milner type systems, ML-inspired languages, immutability, or at least not sharing mutable state. Did Haskell fail? Hmm, let's look at Typescript and Rust.

Don't get me wrong, a Lisp is always a great and fun language, and you can write whatever DSL you might like on top of it. But the old joke that "a Lisp programmer knows the value of everything, and the cost of nothing" still has quite a bit of truth to it.

There are several languages that I could use and be economically successful with, but I refuse to use because I consider them to be poorly designed.

Using a bad language for 8 hours a day makes me irritable and it's impossible to prevent that irritability from overflowing into my interactions with other people. I'd rather that my conversations with the computer be joyful ones.

Most of the time when someone adds these fancy languages what happens is that they leave and the ones left are the ones that have to deal with the shit that was produced.

I'm going through this now, having to deal with code nobody wants to touch because it is overly complex, has no documentation, and is in a language no one else knows. Now, whenever i see an effort like this, to bring an exoteric language for absolutely no good reason, i try to kill it as fast as possible.

I don't want to be the victim of this code in the future or have my team bear the cost of maintaining stuff they don't understand.

I have several decades of programming experience and would never choose Lisp, unless for funny one pagers.

Programming language ergonomics matter and there is a reason why Lisp has so little adoption even after a half a century.

yes. and as a long time lisper, i don't think that it's the macros.

i think lisp's magic is a lot more cultural than most people think. i.e. how lispnicks implement lisps and the ecosystem around it. how easy it is to walk the entire ladder of abstractions from machine code to project specific DSL's. how pluggable its parsing pipeline is -- something that is not even exposed in most languages, let alone customizable.

the language, the foundation, of course matters. but i think to a lesser extent than what people think. (hence the trend of trying to hire lispnicks to hard, but non-lisp positions?)

and it's not even an obviously good culture... (just how abrasive common lispers are? need to have a thick skin if you ask a stupid question... or that grumpy, pervasive spirit of the lone wolf...?)

maybe it's just a peculiar filter that gets together peculiar people who think and write code in peculiar ways.

maybe it's not the macros, but the patterns in personality traits of the people who end up at lisp?

While what you say is true (I’ve used Lisps for 40 years and here I am writing Rust), the people who consciously make that choice are a tiny niche. There are vastly more people who don’t and can’t make that choice because they don’t have 1-3. So the empirical evidence for what’s actually critical is pretty slim.

Reading SICP (and other such mind expansion) has definitely (gradually over a very long period) shaped how I write Python.

C for systems programming, javascript for everything else!

Me with TCL instead of Python. TCL is the weird Unixy cousing. Instead of cons cells and lists, you get lists and strings.

The talk I posted from Alan Kay is the steel man. I think you've missed the essence of TFA because it's not really about Clojure or lisp.
