As a software developer, I completely agree.

As a person who's often tasked with building reports for presentation, and more often, for passing on to analysts to expand on, I find that notebooks give a much more accessible workflow than other options. Excel is way too limiting, most of the downstream analysts aren't software devs and don't have, know, or want to know an IDE. Notebooks give a way to combine graphs, text and code (show your work) in a concise form.
