People dismiss modern notebooks as Knuth's style of literate programming, where they are more for exploring and documenting an existing codebase or just experimenting. So people are often arguing over two completely different things.

I love notebooks, made VS Code extensions for Go (gobook) and for Rust (rustnote). Give them a try if anyone is interested, still lots of features to add, but the source code is standard markdown, so the code results can be saved straight to Github and they render there.
