I like your comment.

But let's take for example JupyterNoteBook. It's nice but not as good Knuth's stuff. Why ? Because the notebook forces you to follow the evaluation order whereas Knuth allows you follow your ideas order. Now for the rest, Jupyter is simply much better. But fundamentally, JNB can't match Knuth's LP flexibility.

So I'd say that JupyterNotebooks are really nice to explain a recipe but LP is better at explaining ideas (more like algorithms).

However, usually algorithms presentations have more to do with ideas, concepts. And thus, one may wonder if even bothering writing an LP document is necessary since the core ideas don't actually need code to be explained).

So-so... :-)
