Docker deploys is a bit like that I think. Overall, I think many languages and programming systems pick up pieces from each other nowadays. PHP almost by accident can be quite stateless. Yet it's looking more like Java. Many things which could be deployed as an executable, are deployed as VM images. I'm sure we can come up with more things...

Common lisp isn't functional in that sense.

Common Lisp is pretty much the opposite of what people think of as functional nowadays. You're constantly changing the image and everything is mutable.

> Personally I think/hope they would have earlier discoveries / more broad usage of the deterministic systems like nix etc, which are built upon functional principles of immutability etc.

Yeah, that, uh, doesn't sound like Lisp

The problem is that the type of developer you're talking about is the kind who invents a thousand excuses about anything. It doesn't begin and end with different languages. Using a different subset of their favorite language? A different toolchain? A radically different build process? You'll hear plenty of whining about it. You put a Lisp or a Prolog in front of them, and their attention flows upwards to the most general principles to whine about. The entire thing is that if you stick them into an unfamiliar environment, they will vocalize their discomfort through rationalization. I think most people who have led teams will know exactly what I'm talking about.

Not that these people are necessarily bad at their jobs, but they're definitely a personality type you should learn to identify so you can manage them properly.

I disagree with this profoundly. There is no argument that Lisp in general can get you in a terrible mess. So can C, or pretty much any language (I well remember a case of 11-way multiple inheritance in C++ game code). If I were running a Lisp-based project, there would be project standards (like no exported macros without signoff, and a list of standard library dependencies), documentation requirements, and code review.

The fact that Lisp is the “programmable programming language” doesn't mean that every engineer should be inventing weird versions of while loops. What it does mean is that a skilled Lisp programmer can build a domain-specific language that substantially helps in development.

One good example of this is the Crash Bandicoot games, along with the same studio's Jax and Daxter, which were built with dialects of Lisp (yes, they had to compile the code, and take care with storage allocation, just like any other game code). Cisco hired Kent Dybvig, principal author of the Chez Scheme system, and open-sourced that software; I have no clue what they use it for, to be honest, but I assume that they had some reason for doing this. Companies using various Lisp languages have been documented in areas from fintech to quantum computing.

I use Common Lisp at work.

>> said: lovely, but I ain't using it at work.

Says who, you? Wrong. I use Common Lisp at work.

edit: and not just use as in a side toy, design and writing software in CL is my primary responsibility. FWIW, at a FAANG!

> The very power of Lisp, macros, dynamic programming, reflection lead to a mess of an ecosystem where every single developer reinvents the wheel and nobody can understand yet another DSL invented by the next developer next to them.

Have you like looked at anything in the Clojure ecosystem because this description makes no sense of any kind. Clojure has macros but less powerful than common lisp and Clojure code in the ecosystem tends to be small and understandable.

Anywhere is where exactly? I've been thinking of where I could use it for like 10 minutes, and I couldn't come up with anything. Maybe a game engine or web services. It wouldn't make much sense for any kind of desktop software or command line utilities that are supposed to start really fast and have minimal runtime.

I have a todo list longer than the Tour de France I want to tackle first!
