As an outsider to the whole notebook ecosystem, I am absolutely gobsmacked that the representation of the notebook makes it possible to have out-of-date intermediate results. Haven't they been around for like 10+ years?

This is one of those things that is blindingly obvious to people in adjacent sectors of the industry, but maybe there just hasn't been enough cross-pollination of ideas in that direction (or in either direction).

For as long as there have been Jupyter notebooks, there have been people saying "Wait, what??" But there have been way more people using them, and finding them pretty effective despite their inherent lack of soundness.

I personally fall into both camps--both horrified at the execution model but also, it's not actually caused problems for me as it's second nature to restart the kernel when changing upstream cells.

That said, marimo feels like a significant step forward and I'm rooting for them to succeed.
