This peaked at a time when microcomputers had not reached the right affordability and power parameters.
People who were developing in Lisp turned their eyes to the microcomputer market and the business to be had there, if the stuff would only run. So there was some activity of rewriting Lisp stuff in languages like Bliss and C.
The transition from powerful workstations (where we can count Lisp machines) to microcomputers basically destroyed everything which couldn't make the jump nimbly.
The new crop of programmers who cut their teeth on micros simply had no knowledge or experience with anything that didn't run on micros.
Poof, just like that, a chunk of the computing sphere consisting of new people suddenly had amnesia about Cobol, Fortran, Snobol, PL/I, operating systems like TOPS/20 and VMS and whatnot.
Only Unix pulled through, pretty much --- and that's because Unix started on relatively weak hardware, and was kept small. Unix started getting complicated approximately in step with micro hardware getting more complicated and powerful. E.g. a Unix kernel was around 50 kilobytes in 1980. not a good fit for some Apple II or Commodore Pet, but not far off from the resources the IBM PC would have.
By the time micros were powerful enough to the huge Lisp stuff with 20 megabyte images, we were into the 90s, and starting to be overrun with crap dynamic languages.
Now Lisp people could have buckled down and worked on promoting excellent Lisps for microcomputers. There were a few fledgling efforts like that that were not promoted well.
It seems that what Lisp programmers there were, they were mostly wrapped up working on bigger problems on larger hardware, and ignored microcomputers.
It's very hard to promote anything today that most of your Generation X (now management class) didn't get to play with in the 80s and 90s.
Nobody in the Lisp world ever took the time to implement stuff that people wanted on those tiny machines. Or to demonstrate to people the cool stuff it could do.
You can see this in Dr. Dobbs Journal. People are doing things like drawing graphics, writing spell checkers and controlling modems. Assembly and BASIC are normal but C and Forth are mentioned regularly. Turbo Pascal pops up in 1984. Some of the names are famous enough that you recognize them even now, decades later.
Lisp just ... gets barely mentioned in passing sometimes. And nobody of note writes anything about it. Somebody could have built a word processor, a spell checker, a chess game, a reversi game, ANYTHING ... but nobody did.
Possible answers:
1. Blacksmiths enjoy making custom tools for each domain while welders just want to get on with solving their domain problem.
2. Blacksmithing is harder to learn. Welding using modern techniques is easy to learn. (Caveat: Welding well is quite difficult. But learning to weld good enough to repair a broken hitch on your tractor is easy.)
3. Welding can solve a very large chunk of metalwork problems. Not all of them--and not always with elegance--but it gets the job done quickly. Blacksmithing can solve a larger set of metalwork problems with more elegance but it also takes more time and skill.
One of the major trends in computing in the 80's and 90's is that high-end systems lost out to the growth in capabilities of low-end systems, and this happens in pretty much every level in the computing stack. Several people responded to this trend by writing articles sniffling that their high-end systems lost to mass market garbage, often by focusing on the garbage of the mass market garbage and conveniently avoiding analysis as to why the high-end systems failed to be competitive in the mass market. The wonders of Lisp is one of the major topics of this genre.
Most famously, Lisp was tarred by its association with AI during the concomitant collapse of AI that led to the AI Winter, though it's less often explored why AI failed. In short, it didn't work. But more than just AI at the time, people also felt that the future of programming in general was based around the concept of something like rules-based systems: you have a set of rules that correspond to all of the necessary business logic, and a framework of program logic that's making those rules actually take effect--you can see how a language like Lisp works very well in such a world. But programming doesn't have a clean separation between business logic and program logic in practice, and attempts to make that separation cleaner have largely failed.
So Lisp has a strong competitive advantage in a feature that hasn't proven to actually be compelling (separating business from program logic). Outside of that feature, most of its other features are rather less unique and have seeped into most mainstream programming languages. Functional paradigms, REPLs, smart debuggers, garbage collection--these are all pretty widespread nowadays. Where Lisp had good ideas, they've been extensively borrowed. Where those ideas haven't pulled their weight... they've languished, and most of the people wistfully wishing for a return to Lisp haven't acknowledged that the limitations of these features.

Lisp’s most successful commercial period was during the 1980s during an AI boom. Companies such as Symbolics, Texas Instruments, and Xerox sold workstations known as Lisp machines that were architecturally designed for running Lisp programs. They had corporate and institutional customers who were interested in AI applications developed under Lisp, including the United States government. Lisp was also standardized during this time period (Common Lisp). Lisp even caught the attention of Apple; Apple had some interesting Lisp and Lisp-related projects during its “interregnum” period when Steve Jobs was absent, most notably Macintosh Common Lisp, the original Newton OS (before C++ advocates won approval from CEO John Sculley), Dylan, and SK8.
However, the AI Winter of the late 1980s and early 1990s, combined with advances in the Unix workstation market where cheaper Sun and DEC machines were outperforming expensive Lisp machines at Lisp programs, severely hurt Lisp in the marketplace. AI would boom again in the 2010s, but this current AI boom is based not on the symbolic AI that Lisp excelled at, but on machine learning, which relies on numerical computing libraries that have C, C++, and even Fortran implementations and Python wrappers. Apple in the 1990s could have been a leading advocate of Lisp for desktop computing, but Apple was an unfocused beacon of creativity; many interesting projects, but no solid execution for replacing the classic Mac OS with an OS that could fully meet the demands for 1990s and 2000s computing. It took Apple to purchase NeXT to make this happen, and under Steve Jobs’ leadership Apple was a focused beacon of creativity with sharp execution. Of course, we ended up with Smalltalk-inspired Objective-C, not Common Lisp or Dylan, as Apple’s official language before Swift was released after the end of Jobs’ second reign.
Some other factors: 1. Lisp was truly unique in the 60s, 70s, and 80s, but it required expensive hardware to run. It would be hard to conceive of a Lisp running well on a 6502 or an 8086. Something like my NeXT Cube with a 68040 would do a much better job, but those machines cost roughly $6500 in 1989 dollars, out of reach for many developers.
2. By the time hardware capable of running Lisp acceptably became affordable, other languages started offering certain features that used to be unique to Lisp. Wanted garbage collection? In 1995 Java became available. Want object-oriented programming? You didn’t even have to wait until 1995 for that due to C++. Want anonymous functions and map()? Python’s popularity took off in the 2000s. Yes, Lisp still offers features that are not easily found in other languages (such as extensive metaprogramming), but the gap between Lisp and competing popular languages has been narrowing with each successive decade.
Alas, I think MS saw the failure of Clojure within the Java ecosystem and foresaw the same if they made a similar effort.
it's a tree. it's just a few operations to transform it as a structure.
There’s a thing I’m whispering to myself constantly as I work on software: “if I had something that would make this easy, what would it look like?”
I do this continuously, whether I’m working in C++ or Python. Although the author was talking about Lisp here, the approach should be applied to any language. Split the problem up into an abstraction that makes it look easy. Then dive in and make that abstraction, and ask yourself again what you’d need to make this level easy, and repeat.
Sometimes it takes a lot of work to make some of those parts look and be easy.
In the end, the whole thing looks easy, and your reward is someone auditing the code and saying that you work on a code base of moderate complexity and they’re not sure if you’re capable enough to do anything that isn’t simple. But that’s the way it is sometimes.
“if you can just trust that chat GPT will later fill in whatever stub functions you write, how would you write this program?” — and you can quickly get going, “well, I guess I would have a queue, while the queue is not empty I pull an item from there, look up its responsible party in LDAP, I guess I need to memoize my LDAP queries so let's @cache that LDAP stub, if that party is authorized we just log the access to our S3-document, oh yeah I need an S3-document I am building up... otherwise we log AND we add the following new events to the queue...”
It is not the technique that has most enhanced what I write, which is probably a variant on functional core imperative shell. But it's pretty solid as a way to break that writers block that you face in any new app.

> What type of person successfully finds simplicity working in C++?
Be the change you want to see!
Every language has the raw materials available to turn the codebase into an inscrutable complex mess, C++ more than others. But it’s still possible to make it make sense with a principled approach.
In the some vein that Python looks simple on the surface, but in reality it is a quite deep language, when people move beyond using it as DSL for C/Fortran libraries, or introduction to programming scenarios.
(It's a classic legend. There is an Islamic legend that Allah gave the first pair of tongs to the first blacksmith because you need a pair of tongs to make a pair of tongs. There's a Nordic legend that Thor made the first tongs. In reality, somebody probably used a bent piece of green wood, which didn't last long, but could be easily replaced.)

Re: "funcall's vibe coding findings", it makes sense that human-style lisp (/tongs) would be too nonlinear for LLMs (or gods like Thor) to generate?
Edit: but in line with latter-day retcons it also makes sense that Thor would get credit for something good that Loki did

Lisp, Jazz, Aikido and (now) Blacksmithing.
The distinction between Lisp and the programming languages widely adopted in the industry is a bit like the distinction between artist blacksmiths and fabricators. If blacksmiths have the skills and technique to transform the form of the metal materials they work with. While fabricators essentially rely upon the two operations of cutting and welding. Blacksmiths will use those two operations in their work, but also have the more plastic techniques of splitting, drifting, upsetting, fullering, etc.

These additional basic tools are created from essentially the same working material, on the fly, just like the tongs in TFA
The root object would be two rocks brought together in a bang heard 'round the world, then perhaps some sharpened sticks, all the way up to a Colchester lathe somewhere in Victorian England and the machinery that made whatever object we're looking at.
which is a multi-volume series based on the fact that a lathe is the only tool in a machine shop which can replicate itself, so the first volume has one make an aluminum casting foundry in one's backyard, the second how to use it to make a lathe, then one can use the rough-cast lathe to improve itself (or make a better lathe), and from there make the entirety of a machine shop.
Blacksmithing as noted in the original article is unique in that it is self-sufficient in a way that few other processes are, and downright elemental in what one needs.
Another book which touches on this sort of things is Verne's _The Mysterious Island_ which has a couple of escaped Civil War prisoners making things from essentially first principles:

Less on the nose are _Robinson Crusoe_ and _The Swiss Family Robinson_, though those have starter kits in the form of flotsam and jetsam (rather more than that for the latter).
That's it, not too complex.
