Average Joe and Susi have been for 3+ decades nicely programming lots of extensions to AutoCAD and its various clones in Lisp.
Generally I agree that Lisp programming is a bit more challenging due to the slight mathematical nature (lambda, ...), code as data and meta-programming.
I don't think that one needs to be a 10x programmer to use Lisp - many of those 10x programmers are not programming in Lisp, since the 10x programmer gets hired because he/she might be able to cope with enterprise Java architectures.
Since Lisp is a programmer amplifier, you might think that these Lisp users are 10x programmers, when in fact they are not.
But there are domains where people are using Lisp, who are not focused on programming. For example there are various Lisp-based music apps + literature which are used by composers. Example: https://opusmodus.com
Ha ha, I read somewhere that years ago, in some org or the other, Emacs Lisp was programmed by secretaries to help them achieve their routine tasks. Apparently they were not told that it was "too difficult for them" :)
I've heard about other tools like this before ([1] for composition, [2] for synthesis, [3] for mind-blowing :-p) but somehow never heard about opus modus before.
* Where did you learn about it?
* Are there other similar prog-lang music production tools with similar level of polish?
* Any cross-platform / Windows supported tools? -- unfortunately opus modus only runs on macs :-(

Opusmodus was supposed to have a Windows version in 'the future', but I don't know what plans are currently.
And there is a limited pool of that.
We, humans, also have work to do.
